SubjectRe: 2.6.0 performance problems

Done.

report1.txt is the result of:
opreport `bk export linux-2.5 linux-2.6-testb`

report2.txt is the result of:
opreport -l vmlinux


The times for this operation is:
real 15m20s
user 0m35s
sys 0m20s


On my main system (1.3GHz Athlon, 512MB memory, fast hard drive; in other
words has plenty of resources) I get similar results, scaled down of
course.

On 2.4 the times are
real 3m47s
user 14s
sys 7s

On 2.6 the times are
real 3m27s
user 14s
sys 7s


I also get 90+ percent iowait under 2.6 and 0 iowait in 2.4. I'm not sure
how the alleged suckiness of 2.6 paging fits into this. On this system
the execution times are almost the same. On this machine, in addition to
the iowait differences, there are cpu use statistics as reported by top.
On 2.4 idle time is 70 percent while on 2.6 the idle time is near zero
percent. I'm not sure what the significance of this is.CPU: PIII, speed 648.072 MHz (estimated)
