[squid-users] Why using LRU?

Hello!

Why is LRU still the default replacement policy; others seem to perform much
better in terms of hit ratios.

http://www.hpl.hp.com/techreports/1999/HPL-1999-69.html even suggests lower
cpu utilization:

"The results indicate that the heap-based implementation of the GDSF and
LFUDA policies consume less user and system CPU time than the original LRU
replacement policy in Squid 2. Interestingly the heap-based LRU
implementation also consumes less CPU time than the original list-based LRU
implementation."

Some comments would be fine!

Regards,
 Michael
