You might also want to comment out the fsync's in the qmail source code. These two changes will let the OS manage the disk buffers instead of flushing them all the time. You'll get much better disk performance. Ken Jones

I've just upgraded to current RC and got quite a load (about 9-10) caused by vdelivermai and vmstat suggests that I got IO bottleneck now. Besides I see lots of vdelivermail running and every mail spends now lots of time in a queue, even when it is local. Any ideas, please? Solt PS Ken, sorry about two copies of this mail. BTW: Could you set default Reply-To: to list address? It would be easier when replying.
