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   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

2.4.11-pre2

   procs                      memory    swap          io     system         cpu

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.
