Just to make sure we're not needlessly suffering, on my fileserver at least (raid5) I found it to be MUCH faster if I increase the raid stripe cache: # boost the raid5 cache size, default is 256 for i in /sys/block/md*/md/stripe_cache_size do echo 4096 > $i done This doesn't help with simple striping, but it helps a lot with redundancy. Also, you should check the dirty ratios (/proc/sys/vm/dirty_*) to make sure (1) there's enough buffer to speed things up, but (2) not so much that a flush (or even a read!) causes a long lockup. Buying more RAM might help too. _______________________________________________ arm mailing list arm@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/arm
