Title: Performance issues

Now that you have these comparisons, I suggest generating a verbose log file and seeing where your time is spent in the Windows Installer. Each action has a start and stop so that should be pretty easy. You may find something surprising (like a CustomAction taking a lot of time or network latency being weird). Or you just might find that copying files with rollback takes longer... <smile/>

InstallShield versions were compressed yes, I ran some tests and here are the results (as accurate as I can get them):

Installsheild Versions:
Product	Size	Install Time
Floodwork	178 mb	2:25.5
infonet mapx	155 mb
infonet mapo	153 mb	1:40.5
infoworks demo	272 mb
infoworks mapx	403mb	2:51.7
infoworks mapo	422mb	2:57.2 (installed without sample data)
Windows Installer Versions:
Product	Size	Install Time
floodworks:	121mb	3:21.6
floodworks tutorial:	38mb
infonet mapx:	78mb
infonet mapo:	83mb	2:15.1
infonet tutorial	22mb
infoworks demo:	222 mb
infoworks mapx	185mb	2:58.9
inworks mapo	190mb	3:01.9
combined infoworks tutorials:	46mb

That will probably read as total gibberish on the mailing list. Aaaaaanyway, the short version is that the performance hit isn't too bad at all, it just seems longer to the people in support because it takes longer to load and doesn't tell them the name of every file it is copying as it does so. There are a few installers that have a heavy hit (the ones in the list are just the main players, there are a load more). I suspect that the stupid slow versions have issues that are as yet unknown. I tried running an uncompressed version and saved about 30 second off a 3 minute install time. Windows installers are certainly slower, but not by much, it's worth the trade off for ease of delivery, not to mention maintenance.

I'm sure this is a problem others have encounted. I have now replace our suite of installsheild products with spanky new WIX versions. I have managed to elimitnate a large amount of redundant code (previous installers copied large amounts of file that were never used). Most of the installers are now half the size in compressed form. Dispite this the installation process now takes longer (so I'm told, I intend to run some performance tests later today). Is there a standard explaination for this that I can give to people (i.e. talk to city hall)

I am playing with the idea of having internal versions (products that will only be used by testers and support staff) as uncompressed in the hope that most of the time is being spent extracting files.

Was the InstallShield package also compressed? Are the tests being run over the network? Sometimes bandwidth constraints make it faster to have a compressed image.
