Is that user or sys cpu time? (what does "top" say?) And is it squid that takes that much cpu time or is that system-wide cpu usage? I don't think squid should take much more CPU time when the cache is filled up but there are possibilities e.g. running squid cache on reisersfs without the notail option... > The timespan involved in the two measurements is only about two weeks > and I cannot think of any other changes to the usage that could have had > an impact on how the box is used in that time period. -- Matus UHLAR - fantomas, uhlar@xxxxxxxxxxx ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
