Linux Test Project suite on 2.4.11-pre2 and 2.4.10-ac4.
vmstat output at the bottom shows free memory and
swap after the runs complete.
Kernel versions: 2.4.10-ac4 and 2.4.11-pre2
.config files: identical
Filesystem: ext2
Distro: Linux From Scratch 3.0
glibc: 2.2.4
LTP version: 20010925
Hardware:
Toshiba Tecra 8000
192 megs RAM
128 megs swap
400 mhz Pentium II
Test process:
boot kernel
login 3 console ttys
run "vmstat 8 >logfile" and tail it
run "for" loop to repeat LTP 3 times and log results
tail -f LTP results files
There were 11697 - 11705 individual tests that PASS
LTP isn't a benchmark, but I grabbed some growfile i/o results anyway.

Some of the growfile commands errored out each time. growfile aborts
when it detect an error. Above the first run on 2.4.11-pre2
completed one growfile command the others didn't.
growfile commands that didn't complete:
growfiles -b -e 1 -u -r 1-49600 -I r -u -i 0 -L 120 Lgfile1
output:

/var/log/messages suggests I'm missing something for a few tests:

That is a snippet from the logfile, not the result of just "vmstat"
Here are some earlier results that were not necessarily using the same
.config file, nor as carefully controlled. I.E. I may (or may not) have
been using the machine during the tests. These were all with ext3.

I'll do a summary from another machine without duplicating to much.
