Title: Performance issues

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

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.
