I ran a bunch of performance benchmarks today and it looks like this will slow our 5.0u7 JRE installation process down by an average of 5 seconds. Here are my 5 tests on my 933MHZ/512MB Dell machine:
Before-fix: 46s, 46s, 45s, 46s, 45s
After fix: 50s, 50s, 51s, 51s, 51s
I guess installshield's lzx is better compression vs rtpatch's compression, but it's slower to uncompress.
So we need to determine whether reducing the JRE 264KB is worth adding ~5 seconds to the install time. Keep in mind that I have a slow 933MHZ machine.
