It looks like Cluster mode has an issue if the node where an object is cached is down/offline. I took one of my nodes offline (which had already cached a test object) as a test and the other nodes then performed quite badly (ie, took several seconds) - perhaps timing out? - before responding... and they did this consistently without improving over time. Only once the down node was brought back up did things become snappy again. I also noticed they did not re-cache the object but *always* went direct to the origin. Would this behaviour not be a problem if one of the nodes crashed? Should an existing node then not re-cache an object to ensure optimal performance? I'm currently using 3.0.1. You mentioned trunk - where can I find what improvements you've made to Cluster mode? Thanks h
