Linux Test Project suite on 2.4.11-pre2 and 2.4.10-ac4. This isn't a duplicate. This machine recently had reiserfs errors during LTP. Here are tests with ext2. (I'm re-running ltp on reiserfs too) Kernel versions: 2.4.10-ac4 and 2.4.11-pre2 kernel .config: identical Filesystem: ext2 Distro: Linux From Scratch 3.0 glibc: 2.2.4 LTP version: 20010925 Hardware: AMD Athlon 1333 mhz IWill KK266 motherboard 512 megs RAM 1024 megs swap 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 light use of links and irc clients. no X. There was a PASS for 10670 to 10676 tests. LTP isn't a benchmark, but here are some growfile i/o results: Linux rushmore 2.4.10-ac4 941824 iterations on 41 files in 760 seconds Linux rushmore 2.4.10-ac4 939209 iterations on 41 files in 760 seconds Linux rushmore 2.4.10-ac4 932649 iterations on 41 files in 760 seconds Linux rushmore 2.4.11-pre2 914028 iterations on 41 files in 760 seconds Linux rushmore 2.4.11-pre2 920055 iterations on 41 files in 760 seconds Linux rushmore 2.4.11-pre2 924409 iterations on 41 files in 760 seconds All growfiles commands completed successfully!

It is not the result of a single iteration of "vmstat". Here are some earlier results that were not using the same .config file. In these tests I was playing mp3's, running top, ps, etc watching what the tests do. These were all with reiserfs.
