Re: [WiX-devs] WiX v4.0 Default Compression Level?

[Chris D. <csd...@gm...>]

With cab count appearing to have even more of an impact on link time than
the compression level, I agree that halving it to 100MB is a good idea.

I think whether different defaults can be used for Debug vs. Release builds
could somewhat determine what the best default values are.

   - If the same defaults are to be used for both Debug and Release,
   sticking with MSZip seems like the best option (based on a very simple
   lower-is-better ranking using [Link time] * [Cab size]). Changing from
   MSZip to Low wouldn't be terrible, either, but does result in a ~50%
   increase in link time for only an ~11% decrease in file size.
   - If different defaults can be used for Debug vs. Release, then I still
   think using None for Debug and High for Release would be ideal. Releases
   are often copied/downloaded many times, and dealing with a lengthier build
   process a small number of times to benefit from smaller file
   copies/downloads many times seems worth it to me.
