need better I/O scheduler for bulk file serving
Quoted 4 lines · Felix von Leitner
When three people are downloading different images (my server "only" has 512 MB RAM, so it can't hold even one of the images in memory) at the same time, the bandwidth utilization goes down to 6 MB/sec on my fast ethernet NIC. The hard disk appears to be busy seeking.
Try RAID1.
it sounds like it's just slow disk. our redhat mirror held steady at about 89Mb/s during the rh9 release. using 2.4.18 384MB of ram and a 4x120GB sw raid5 stripe with 64k block size.
