My improvements were closer to 5%. I use VS2013's amd64_x86 cross-compiler. I didn't touch the -FS flag (I imagine it just becomes meaningless).
Debug build, before: build 17:06, objdir 3.83GB Debug build, -Z7: build 16:06, objdir 5.22GB Opt build, before: build 17:47, objdir 3.01GB Opt build, -Z7: build 16:59, objdir 4.43GB I used the opt Z7 build for a bug investigation and, at least at first glance, I didn't notice any problems with the debugging information.
