Hi Octavian, Like Seth said this was very nice to install and run. But I think I'm doing something wrong. I cloned the lkl/linux git tree into a 9G ext4 loopback file, both one mounted with lkl and one mounted as loopback. The results were worse than I expected - loopback was 0m10.078s for clone and 0m0.877s for rm -rf; lkl was 5m5.625s for clone and 0m44.332s for rm -rf. I assume this has to do with the 100MB buffer and subsequent thrashing? How should I tune this to make it perform better? No crashes from this, though. thanks, -serge -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
