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. -- Tomasz Chmielewski http://wpkg.org
