Entropy running low is a frequent and actual problem for me on virtualized or headless servers serving https content. It slows everything, including ssh, to a halt.
You can see your current entropy level, which is probably high due to having a keyboard, with this command:
cat /proc/sys/kernel/random/entropy_avail
You can watch this number drain by reading from /dev/random continuously.
