Subjectltp on 2.4.11-pre2 and 2.4.10-ac4 (athlon on ext2)
From

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!


Unique test PASS

1st 2.4.11-pre2 run
recv01 3 PASS : invalid recv buffer successful

Unique test failures

1st 2.4.10-ac4
nanosleep02 1 FAIL : Child execution not suspended for 5 seconds
nanosleep02 1 FAIL : child process exited abnormally



vmstat steady state after the three runs:

2.4.10-ac4

procs memory swap io system cpu
r b w swpd free buff cache si so bi bo in cs us sy id
0 0 0 266620 68132 157876 11848 0 0 0 0 104 71 0 0 100

2.4.11-pre2

procs memory swap io system cpu
r b w swpd free buff cache si so bi bo in cs us sy id
0 0 0 12808 483932 2188 14368 1 0 1 0 103 71 0 0 100


That is a snippet from the logfile after 3 runs completed. 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.
