I'll try and report back. Just curious, what is the difference between boot-time setperf calculations (which leads to 99) and post-boot sysctl juggling (which successfully cranks to 100 in most cases)? For me, it looks like boot-time and post-boot use different assumptions and/or algorithms. Why boot-time setperf code can't do same ?->0->100 transition without making (wrong) complex assumptions?
