Currently, the trend with CPUs is to add more cores rather than increase

This does not scale very well with certain things in the Linux kernel.
One of them is kcryptd.
A system able to deliver data with a speed of ~200 MB/s from a RAID
array, will be only able to deliver a fraction of it (i.e. ~40 MB/s in
my case) when reads are being done from a dm-crypt device.

Anyway, it is not highest priority currently... but still in slow progress.
(but I guess high speed SSDs will increase priority for this too,
currently it is real problem only for RAID arrays:-)
And, laptops/netbooks with (slow) multi-core CPUs.
Encryption is getting popular there as well.
