Bob and I are having a little conversation on a pull request about
what the default compression level should be in the WiX toolset:

Historically, we used mszip which I **thought** was generally derided
in this day and age in favor of LZX (low, medium, high). I'd be happy
to be wrong about that.
My thinking was by default we should opt for the best compression. Of
course, that means the slowest build times. There are reasonable was
to control compression (WIX_COMPRESSION_LEVEL env var and --dcl
switch) to override that, say to set it to "none" on build machines.
One thought is to set "-dcl" to "none" in Debug builds by default?
Anyway, I'm looking for suggestions? What do people think we should
default the compression level to in WiX v4.0 (since we can change it now).
Thoughts?
We could do a simple benchmark (say, 100MB, mix of binaries and text) to
see if, across a couple of scenarios, we hit a common "win." We're not
going to cover every scenario but it should do to pick a default.
I definitely approve the idea of default "none" compression for debug
builds. In v4.x with hard links and proper use of obj\ and bin\, it
should work really well.
