Very slow decompression

[wyzerd]

This problem existed back around version 6 it has returned with 9.7. The installation is taking an extraordinary amount of time without progress indication.

You will find the log file attached that will show the 3GB installation took 21 minutes. this in itself is a problem, but even worse is that there was no indication that it was actually doing anything.

It starts with a full minute of Windows installer is preparing.. then 5 minutes of Training Data estimate installation time of 707464 minutes to complete. then switches to 0 seconds for the remaining 15 minutes.

Hello,

I'm not sure why you are encountering this behavior. Can you please generate and attach a verbose log of the installation or send it us to support at advancedinstaller dot com so we can investigate it?

All the best,
Daniel

This was from a brand new installation package created in 9.7 instead of the updated one I used last time.

[wyzerd]

I used the new install on another machine to see if it would help.

At first it gave this:

Then went to 182 Minutes after about 10 minutes then to a more accurate reading when about 5 minutes were left.

I still don't have all the details needed to make the call on exactly what causes this problem. I have noticed that the amount of data in this product had doubled since the last release.

I suspect, 7z does some very odd caching and it is causing a disk swap once memory is exhausted. Changing the mechanism from LZMA to CAB and One CAB per feature, did fix the issue for the time being. (I also checked Compress CAB files.)

[Daniel]

Hello,

I'm afraid this is a Windows Installer behavior. Please keep in mind that we are using Windows Installer API functions for time remaining estimation. Also, regarding the archive type (CAB or using LZMA compression) there should be no difference during a first time install between their time remaining estimation because when using LZMA compression the files extraction is performed before the installation starts.

All the best,
Daniel

[wyzerd]

Yes, I am sure that LZMA is not the root cause of the problem, but since that one file was allowed to grow to over 2GB, I suspect that is what caused memory saturation and disk swap. CAB didn't really fix the problem, the part that reall fixed it was the seperation of the compressed bits into smaller files. By stretching these into 5 or so files, it was able to complete decompression without having to resort to disk swap. If LZMA could be modified to limit size for an individual file, the performance would be greatly enhanced.
