Walt, a possible reason is that fsync is much faster in Linux-2.4 than in 2.2. Check that the combined size of your log files is 50 % - 100% of the buffer pool size. Small log files cause more disk i/o and more fsyncs. The kernel 2.4.4-SMP-64GB has been very stable on our 2-way computer. Somewh

2002-01-09 Thread Weaver, Walt
Anyone else out there been playing with the new Linux 2.4 kernel? I just upgraded a test server from 2.2 to 2.4 and reran some of my InnoDB tests. The results were dramatic; updating a 600,000 row table went from 21 minutes and change to 6 minutes and change. Haven't tried 2.4 and MyISAM tables
