<tt>Here are some benchmarks I ran last week:&nbsp; I think it's important
to balance the -s&lt;size&gt; with the -n numbers so that you are
dealing with the same amount of data, otherwise caching can bite you
and you can have misleading results.&nbsp; Therefore, I used 10k file-size,
and adjusted the number of files to give approximately the same amount
of megabytes that was specified with -s.&nbsp; IE; 200MB of block IO and
200MB of small-file io.&nbsp; I only did raid5 vs single disk comparisons on
200, 800, and 3200mb data points, for time reasons :-)<br>
<br>
I think these results show two things going on.&nbsp; 1) the steady decline
of ext3 performance as # files increase.&nbsp; 2) that raid5 and multiple
disks really <i>doesn't</i> significantly increase read performance
for small files. 3) once you're outside the caching zones things go
badly: get more ram :-)<br>
<br>
Then again, my hardware might just be shoddy :-)<br>

  <br>
  <br>
Notes:<br>
The 3ware card is somewhat bus limited because it's in a 32bit PCI slot
in a 64<br>
bit slot I'd expect better sequential read performance.&nbsp; This also
drives up the<br>
CPU number due to bus contention.<br>
  <br>
The read numbers for ext3 and raiserfs look suspect <br>
  <br>
Stripe size for the 3ware raid 10 is 256k<br>
  <br>
all file sytems were live and had other files on them - virgin file
systems may<br>
perform very differently..<br>
&nbsp;<br>
Conclusion:<br>
ufs2 is pretty similar to ext2 if not a little better but not as fast
as raiser4.<br>
  <br>
sync is a big drag but async makes almost no difference over soft
updates.<br>
  <br>
atime/noatime doesn't make a whole lot of difference on this test.<br>
