I am extracting from a large tar file, and at around the 2nd gig, my computer starts to slow and even freeze up a bit. Mouse always moves fine, but that’s about it.

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?
