[Bug 246413] Re: kcryptd process doesn't utilize multiple cpus

My CPU is capable of 130MB/sec AES-256. My drives, 119MB/sec write.
Combine this into a dm-crypt volume: 11MB/sec (eleven megabytes per
second [!]). Uh, this thing seems broken to me.
I'm using xfs on dm-crypt.
Anyone know if iostat can provide some useful information? I'm
wondering about I/O thrashing like we have been seeing with grub and apt
lately. Something is/was seriously wrong with those too.
