What do the new epoll and COSS options offer to me as the administrator of a lightly-loaded Squid server? Anything? I usually read of epoll in the context of being recommended for a Squid server with very high CPU utilization. I'm not clear on the advantages of COSS over other disk storage schemes. I am currently using UFS on a single ReiserFS-formatted cache, on Linux. This setup is working fine, but I am always looking for improvement. (Given that I do not suffer from high CPU use, improvement would be defined as reduced latency in cache look-ups.) Any thoughts on what these new option might mean for a lightly-loaded server? Thanks.
