because of a) Squid's select/poll loop is not very efficient and starts wasting a lot of CPU when there is a lot of open connections b) even poll (which is much better than select) has noticeable scalability issues wasting a lot of CPU when the number of open connections is large. The epoll patch addresses both of these if you run on Linux-2.6.. Regards Henrik
