Hi everyone, Since upgrading to Kubuntu 14.04 I've had an issue with Quassel irc client being slow on startup when it retrieves backlog from database. I've tracked it down to different sqlite version being installed. Previously I had 3.7.17 and now have 3.8.2. I've tried various versions from https://launchpad.net/ubuntu/trusty/+source/sqlite3/+builds and can only pinpoint it to between 3.7.17 and 188.8.131.52 because there doesn't appear to be intermediate builds.
I don't know what exact queries Quassel runs but most likely (after looking at some Quassel source on github) it's something like the following for a single channel: SELECT messageid, time, type, flags, sender, message FROM backlog JOIN sender ON backlog.senderid = sender.senderid WHERE bufferid = 102 ORDER BY messageid DESC LIMIT 100; When I run this query on 3.7.17 it returns nearly instantly. When I do it on 184.108.40.206 or 3.8.6 which I also tried then it takes about 4 seconds on my not so fast spinning drive laptop. I've posted example database (minimized from original) at https://docs.google.com/file/d/0Bzx3gCDqfzVdcDNhdzlfVlh4ZTA/. Could someone either confirm or prove false that this query has become slower with newer versions?
