regex processing speed

Which is faster:

refresh_pattern/i \.(gif|jpeg|jpg|xbm)$ 10800 90% 43200

OR

refresh_pattern/i ^http://.*\.gif$ 10080 90% 40320
refresh_pattern/i ^http://.*\.jpeg$ 10080 90% 40320
refresh_pattern/i ^http://.*\.jpg$ 10080 90% 40320
refresh_pattern/i ^http://.*\.xbm$ 10080 90% 40320

I ask this because I recently changed to the first one in my squid.conf
file and noticed that the squid process was taking up more CPU time than
before. (Although it could have been something totaly unrelated to this
change).

Thanks,
