As you can see, there's something DEFINATELY wrong here =)


* NOTES:

The old test at the top with the old format are from contest 0.22, the new
results seen below are 0.34.

<conman_work> yes, but results from different versions of contest are
incompatible

<ShawnCONSOLE> riel uses EXT3
<riel> my cpu is slower
<ShawnCONSOLE> but you have fast disks?
<riel> so it doesn't fall idle as quickly as yours, when waiting on the disk
<riel> not very fast ;)
<riel> old 8 GB IDE disk
<ShawnCONSOLE> so having a fast disk and a fast CPU causes the cpu to wait
longer cause the disk finishes its tasks much faster then the cpu expects?
<ShawnCONSOLE> mem_load final test = 78%
<ShawnCONSOLE> so final numbers:
<ShawnCONSOLE> 99, 80%, 87%, 83%, 75%
<riel> yes, a very fast CPU falls idle more quickly
<riel> but it's very curious that ext3 is _that_ much worse than ext2
<ShawnCONSOLE> thats much better.
<riel> definately worth pointing out to the ext3 maintainers
