we're running Cyrus 2.2.12 on a server with many virtual domains and users. currently, we're using quotalegacy, but running quota(8) requires reading many directories (1736 to be exact) to enumerate the quota roots (keys) and opening the quota file for each of more than 100k users. usually, this completes in 1-2 minutes, but during high I/O load on the system (backup), it can take 15 minutes. so I wonder, will skiplist be a better choice? obviously running quota(8) will be a very cheap operation, but I'm worried about contention on the quota database during delivery etc. (these users are for the most part not actively using the system -- they get less than one message per day each(!) -- so I probably worry too much.) also, will the skiplist file get fragmented? if so, is there a tool to defragment it? -- Kjetil T. ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
