Running Ubuntu 9.10 With Older PC Hardware
With the random write performance through AIO-Stress, Ubuntu 9.10 had identical performance to that of Ubuntu 8.04.3 LTS with a speed of 13.53MB/s. Ubuntu 8.10 and 9.04 were lower at just 8MB/s.
Ubuntu 9.10 experienced another setback with its disk performance when it came to Dbench and running six clients. Between Ubuntu 8.04 and 9.04 the performance was all around 26MB/s, but with Ubuntu 9.10 this regressed to 18MB/s.
Our Apache test profile does not really stress the disk, but with this test profile, it exhibited a massive performance drop under Ubuntu 9.10 with this older ThinkPad notebook. Ubuntu 9.04 was able to average 4808 requests per second while Ubuntu 9.10 had just 456 RPS. We are currently unsure of what is causing this substantial drop in server performance.
