I just started SPSS 24 from scratch (Win7 Pro: 64-bit; i7)
It took exactly 60 seconds. Closed SPSS. Double-clicked on a 1.2 gb *.sav file (102900 cases and 11590 variables) It opened in 8 seconds. Analysis is ridiculously fast: what have they done to it?

J.D. That twitter thread is a truckload of bollocks.
My first start from click to UI presentation was a mere 44 seconds. Exit and restart 8 seconds. I don't need to go fetch coffee. I suspect the people posting on that thread have other systemic disorders. Go learn R. ROFLMFAO. --- J.D.

What are your system specs and what version of SPSS are you using.
Speaking generally, SPSS has always opened slow relative to Mplus/R (haven't used others). I find the thread largely consistent with my own observations and annoyances. And I do regularly use R and Mplus along with SPSS so, FWIW. -- Sent from: http://spssx-discussion.1045642.n5.nabble.com/ ===================== To manage your subscription to SPSSX-L, send a message to [hidden email] (not to SPSSX-L), with no body text except the command.

I agree JD, I likewise use SPSS, Mplus and R in roughly equal
proportions. SPSS 25 is the worst of any editions of any of those 3 packages for opening speed. Takes 3-5 minutes on my fairly powerful laptop. Mplus is a split second. R seems to vary, but generally less than a minute. On 06/03/2019 12:32, J.D.

I just tested mine on my laptop. 39 seconds from click to UI. It was 40 seconds for Excel to open with the RealStats extension. At the University of Michigan using AppsAnywhere, it's 41 seconds for SPSS. So I would echo David. There must be some systemic underpinnings to the difficulty.

There is one thing you can do that might speed up the startup. By default, Statistics starts up a process for the help system as well as the main processes. You can stop this as follows. Create environment variable "SpssLoadHelpOnStartup" and set it to anything other than 1 or [yY][eE][sS] windows: set SpssLoadHelpOnStartup=no mac: SpssLoadHelpOnStartup=no ; export SpssLoadHelpOnStartup If you later access the help, the process will be started at that time. You can, of couse, do this setting (on Windows) via the Control Panel so that it is always in effect. The exact way to access environment variables varies across Windows versions, but on Win 10, right click on Start, choose System, and type environment in the search box. It can be either a system or user variable. I don't know how much time this will save, but it used to be significant enough that this suppression mechanism was created. On Wed, Mar 6, 2019 at 7:51 AM Dates, Brian <[hidden email]> wrote:

I believe that the loading speed has much more to do with speed of the hard
drive than the processor or other computer hardware, since loading new programs is about reading code from the drive and placing it into RAM memory, but not doing computations with that code. The speed of the analysis, however, should be about the speed of the processor, speed/amount of the memory, and the way that the analysis software handles the actual data (e.g., takes the data from the hard drive for each analysis or places the data into the much faster RAM memory). If I remember and understand correctly, Stata does fast analyses since it can place all analysis data into memory while most other programs take larger data sets from the hard drive, which is much slower. Stata can potentially fail to work, however, if it's on a 32 bit computer without very large amounts of memory and one tries to work with an extremely large dataset (e.g., the Chinese census), since 32 bit computers have much lower limits to how much memory they can deal with. ...but back to the main point, I'm just now noticing what the rest of you were discussing after re-installing my operating system on the same W10 i5 computer and re-installing v.25. The old installation was on a 3 hard drive RAID 5 system with 3 fast solid-state drives (hard drive read speed should be at least twice what is typical from a fast drive) while the new installation is on a single hard drive system. I didn't notice SPSS's load speed to be slow at all under my old RAID system, but now I understand everyone's complaint when I'm using only a single drive. My load speed was around 1 minute with the single drive, while I never noticed anything slow before with the RAID. I might just have to transfer the OS and my programs back to the much faster hard drive system. Some of the newer computers are now using newer hard drive technology with what's called PCIe hard drives, which are much faster than even the solid state drives. So if you want faster load speed,s the first thing to consider is a new, more modern solid state hard drive (SSD) to replace an older rotating hard drive in an existing computer (unless you already have one), or going with a newer computer with even more modern hard drive technology. And if you want even more speed, look into adding a second SSD hard drive into what's called a RAID 0 system, which spreads data onto two (or more) hard drives in a way that almost doubles the read speed (and thus load times) from the hard drive(s). If you want to go more elaborate, look into a 3 drive RAID 5 system that will double your speeds while also permitting one of the drives to fail without losing your data/system. ...or go really crazy with something even faster by adding more drives. All of these later options are much cheaper than buying a new machine.

The behavior of the underlying OS complicates this analysis. Windows will often cache program dlls and even data in memory if that memory is not needed by other processes. That is why reloading Statistics not too long after a previous session is much faster than the first time. And if the OS has cached the data in memory, running through it can be almost as fast as just storing the data in memory. However, this depends on how smart the OS cache management is. If it just uses a LRU (least recently used) algorithm to discard data from memory when needed, it is exactly backwards, since the most recently used data will be the farthest away from reuse in a sequential pass. Of course, an SSD can help greatly, as Jeff pointed out. It may be advantageous in some usage scenarios to have Windows preload Statistics when Windows boots. On Windows 10, you can do this as Microsoft explains here. Data compression also trades off the speed of transferring data into memory by reducing the volume at the expensive of cpu cycles to decompress (and compress) data. If you compare zsav format with sav, you will often see a large reduction in file size but not necessarily an increase in processing speed. And even more so if you used uncompressed sav's (but nobody does that anymore). The virtual active file (VAF) structure that SPSS uses for data interacts with data transformations to minimize file rewriting that would otherwise be required to store transformed data prior to a final save. Also, some procedures in Statistics are multithreaded, so they can use multiple cpus simultaneously if they are available. You can study all this through the Task Manager and Resource Manager tools on Windows. There is a setting for cpus in Edit > Options > General, but the automatic setting is usually best. Of course, pulling data from a database or non-SPSS format adds external source overhead. The CACHE command can help with that if running multiple procedures.

Well, I have most of the latest hardware (ok it’s a year or so old now) with NVMe M.2 drives and all the like - I can tell you for me it makes no difference - I start and stop the program
so many times a day I lose track - and the time it takes to open varies - from a few seconds to 1 minute or 2 - I don't know why such variance .. I'd live with it BUT FOR ONE THING - How long have they touted the wonderfulness of multi-tasking ... the problem here is that DANG program LOCKS the computer from doing anything else while it starts - so you just have to
sit there and wait. Let's do some math -- I wait say an average 5 mins a day = 0.666 hrs * 6 days a week * 52 weeks a year = more than $2,500 a year - just wasted – and that’s conservative. ********************************* Notice: This e-mail and any attachments may contain confidential and privileged

Hmm. I guess because I have been doing this long enough that there was a time when you just didn’t want anything else taking resources away from immediate task at hand. The other thing is – there are clear bugs in the program related to releasing (or somehow dealing with) resources – that – I frankly I NEED to or WANT start fresh as often as I can. ********************************* Notice: This e-mail and any attachments may contain confidential and privileged

On Behalf Of Jon Peck The behavior of the underlying OS complicates this analysis. Windows will often cache program dlls and even data in memory if that memory is not needed by other processes. That is why reloading Statistics
not too long after a previous session is much faster than the first time. And if the OS has cached the data in memory, running through it can be almost as fast as just storing the data in memory. However, this depends on how smart the OS cache management
is. If it just uses a LRU (least recently used) algorithm to discard data from memory when needed, it is exactly backwards, since the most recently used data will be the farthest away from reuse in a sequential pass. Of course, an SSD can help greatly,
as Jeff pointed out. It may be advantageous in some usage scenarios to have Windows preload Statistics when Windows boots. On Windows 10, you can do this as Microsoft explains here. Data compression also trades off the speed of transferring data into memory by reducing the volume at the expensive of cpu cycles to decompress (and compress) data. If you compare zsav format with sav, you
will often see a large reduction in file size but not necessarily an increase in processing speed. And even more so if you used uncompressed sav's (but nobody does that anymore). The virtual active file (VAF) structure that SPSS uses for data interacts with
data transformations to minimize file rewriting that would otherwise be required to store transformed data prior to a final save. Also, some procedures in Statistics are multithreaded, so they can use multiple cpus simultaneously if they are available. You can study all this through the Task Manager and Resource Manager tools on Windows.
There is a setting for cpus in Edit > Options > General, but the automatic setting is usually best. Of course, pulling data from a database or non-SPSS format adds external source overhead. The CACHE command can help with that if running multiple procedures. On Tue, Mar 19, 2019 at 4:28 PM Jeff A <[hidden email]> wrote:

Everything Tim said well put. I would also surmise most folks using SPSS
aren't running RAID multi-drive systems although there will be substantial variation in the quality of the 'average' system it is running on. I myself have an SSD (single SSD) on a fairly strong i7 laptop system and it takes 1 minute + cold opening so I mostly just leave it on when using it, but I don't prefer that course of action for several reasons. In contrast, opening Mplus or R is like under 10 seconds, every single time. -- Sent from: http://spssx-discussion.1045642.n5.nabble.com/ ===================== To manage your subscription to SPSSX-L, send a message to [hidden email] (not to SPSSX-L), with no body text except the command.

I kind of ignored this thread, but all of a sudden my laptop started to do this, too! Takes a few minutes to launch SPSS (even after a fresh restart), and while it's warming up, the computer is in frozen mode - can't do anything else. Dell XPS 13, a few months old, i7, SSD, etc., ver. 25, no problems up to now with SPSS, no problems (yet?) with any other software.

Trouble is you can't teach Mplus or R to absolute data analysis beginners in
13-week semesters, including assessment. I'm sticking to SPSS 24 and *.sav, *.sps.

No comment re Mplus. But I think that many people *are* (no pun intended)
successfully using R for one-semester introductory stats courses. Several GUIs for R are available too. Some of them are listed on this page: https://www.linuxlinks.com/guisforr/ I am only a very occasional useR, but I gather that for an introductory course, R-Commander (by John Fox) is a nice choice. https://socialsciences.mcmaster.ca/jfox/Misc/Rcmdr/ John F Hall wrote > Trouble is you can't teach Mplus or R to absolute data analysis beginners > in > 13-week semesters, including assessment.

For basic stats, possibly. For a course involving exploration,
comprehension and secondary analysis of a major data set (e.g NORC GSS, European Social Survey, British Social Attitudes Survey) to answer substantive and theoretical research questions, plus the production of a short report using variables and hypotheses of a student's own choosing, probably not.
