iotop reports dm-crypt is the only thing and is using 99% of my
read/write. htop shows minimal processing being used and ram isn't
full...
So... can dm-crypt as full disk encryption slow the computer to
almost freezing?
Potentially, but I've never seen this happen. My experience is with
just dm-crypt by itself on partitions on USB2 disks, no cryptsetup or
any of the friendly wrappers. Are you using dm-crypt by itself, or
LUKS, or something else entirely? Which CBC? Is LVM or RAID involved?
Seeing anything in dmesg about disk errors? Are you using ext34, or
something else?
