Redhat's 2.4.18 kernel has _tons_ of 2.4.19 stuff in it. 2.4.19-pre5 introduced a bug in the I/O elevator which will give you, theoretical ;), more performance, but also pauses/stops while doing disk I/O. This is not fixed yet, even not in 2.4.21-pre5 or -BK (upcoming -pre6). There are some hacks which makes those pauses/stops going away but also drops throughput. Those hacks, each one is somewhat different, are included into the -aa tree, -ck tree and my -wolk tree. > Has anyone else encountered this? Do you have any recommendations? Well, use 2.4.18 vanilla or one of the tree's I mentioned above. ciao, Marc -- Kernelnewbies: Help each other learn about the Linux kernel.
