Hi all, Last night I upgraded our squid proxy from 2.6.STABLE5 to STABLE9. This morning I notice that the TCP_MISS rate has jumped to 47%.... Have I missed something I should have done during the upgrade? Other info: -Cache dir type = aufs -The original install was via yum so the upgrade was via yum. No problems during the upgrade and nothing else was changed. Only 'squid stop,' 'yum update squid,' 'squid start' and done. -In Cache Manager.info the select loop time was around 50-60 ms avg It is now 167.532 ms avg (Don't know what this means or if it is relevant to this issue.) -Nothing out of the ordinary appears in the logs (unless I need to look for something specific). Thanks, Chris
