from kernel 2.6.33 on (at least up to 2.6.37) the access time when using dm-crypt on SSD is way too high. I would expect it to be a bit worse than directly accessing the device (~0.2ms here), but currently it's at exactly 10ms (except a few outlines). This corresponds to CONFIG_HZ=100.
I have similar problems, but 2.6.32 is also affected for me. Look details here: https://bugzilla.kernel.org/show_bug.cgi?id=17892 -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
