I recently came across a replacement for /dev/urandom called frandom
that the author claims is 10x faster on i686 hardware. Based on my own
tests within a VMware Player VM, frandom can generate 150MB/s when
piped to /dev/null. Tests on writing to disk were a modest 50MB/s
which is about all what my laptop's disk can handle.
