Hi, I'd like to test-drive the new ban_lurker_sleep param, but the man page is rather thin on details here. Even after reading the code, I'm not quite sure what the lurker thread does exactly between the sleeps. Is it (a) fetching the last ban and testing all objects which haven't yet been tested against it? Looking at the while-loop in http://varnish-cache.org/browser/trunk/varnish-cache/bin/varnishd/cache_ban.c#L521 it seems to me that it (b) always just checks one object at a time, which would be rather pointless for a cache with a million objects and the sleep-param set to >1 second.
So, what does it really do, and can I expect this new feature to help me given a cache with >1M objects and a purge list which regularly grows over 250 entries. Cheers, Sam
