The files are 26814958 x 4 lines long.
These are the commands that I used and the time statistics. Clearly a massive difference. Not really sure why. This is perl, v5.10.0 built for x86_64-linux-thread-multi
If you've any suggestions for me to check out on the system that I'm using let me know. This is the OS: SUSE Enterprise Linux SP2 64bit
