Hi, Some good news. I finally found that annoying CFS bug. http://article.gmane.org/gmane.linux.cluster.ssic.cvs/8048 In some cases (mixed workload on ext3 hard mounts over drbd over md in my case) read/write performance at CFS server increased over 10,000% (one-thousand percent) with my bugfix. I still need to handle the wbc->nonblocking case. Roger |

This fix may apply to SSI-1.2 as well. On 7/4/06, Roger Tsang <rog...@gm...> wrote: > Hi, > > Some good news.
