Just for the record, I've been running WITH_DYNAMICROOT since nearly the day it came out and don't *notice* any problems. Mostly because the noise of dynamic linking overhead gets lost in the noise of "my hardware sucks so bad I have to take a vacation during buildworlds." My startup takes upwards of 5 minutes anyway, another 45 seconds won't even make me blink. I'm certainly not complaining about the performance :) I only posted those numbers to: 1) Give real world numbers, not "interesting but unrealistic numbers" 2) Show that even worst-case numbers weren't on the level of 40% slowdown. 3) Hopefully help someone figure out where to best improve the dynamic linker. --Mike
