Just as an example I decided to try this out with a large installer of ours (900 MB uncompressed, 400 MB MSI with embedded CAB).
With a single Media Element (CompressionLevel="high") it took 23 minutes to build (approximately). As I've a quad core CPU (Intel Core2 Q6600 running at stock 2.4 GHz per core, unfortunately I'm not allowed to overclock my office machines) in my build machine I added 3 more Media Elements as per the original & simply incremented the Id's & appended the number to the Cabinet attribute. The installer in question is conveniently split into 4 main areas. I modified the DiskId attributes on the Components within 3 of those areas so they changed from "1" to either "2", "3" or "4". This was roughly a couple of minutes work using the find & replace tool in Visual Studio (simply changing DiskId="1" to DiskId="[2-4]" in 3 Fragments, easy when you have 1 Fragment per file). I then rebuilt the MSI & the build time is now 12 minutes (approximately) so a couple of quick changes has almost halved the build time. Looking at the CPU history in Process Explorer it doesn't run 4 threads for the entire build time, it drops to 2 threads about 40% through. The files for the cabs are split into 350 MB, 290 MB, 180 MB & 90 MB uncompressed so a more even split would likely further reduce the time taken. Bear in mind that different compression levels & greater/fewer CPUs will give different results. I used the Visual Studio 2005 IDE to build my .wixproj in all tests. If only I could get the same sort of improvements out of msimsp.exe too (can't even use MSI v5.0 msimsp.exe with this installer as it crashes while v4.5, v4.0 & v3.1 work quite happily). P.S. I would've posted this as a comment on Bob A's blog but comments are closed on the article linked below.
