I'm not shure at all what causes the behaviour you encounter, there is the device-mapper, the crypto layer, the disk scheduler and a lot more which could be more or less related. There was a similar monster thread some months ago on latency issues (which was not crypto related!), Linus did a "yum update" in the background while reading mail with Alpine and encountered some severe stalls. A lot of work has been put into cfq afterwards, and latency is a still ongoing issue in the Linux kernel and on the lkml (see the patch from M. Desnoyers which came up today regarding sched granularity). In a nutshell: I don't know :-) _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx http://www.saout.de/mailman/listinfo/dm-crypt
