All,I am looking for ideas on ways to avoid this, as the tuning guides I have found lead me all over the place. What I am seeing is over time the cache starts to slow down from being lightning fast to being ok, to it taking 1-3 minutes to decide to load, and I know it is tunable on this side. Usually this is fixed by a restart of squid, and everything is happy for a variable time frame. I have a tiny user base (on average 2 people) since this is on a home system.

Any suggestions would be appreciated. Thanks in advance, ~Seann
