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
