I think it's --with-mboxlist-db=skiplist I still use 2.1 with bdb myself, but a quick search of the archives (I love squat indexes - <1s search on a 4500 message mailbox over a 512k WAN) suggests that's correct. doc/text/install-perf confirms it. It doesn't seem to show up in ./configure --help , though. AFAIK skiplist is the default if bdb isn't specified. > It seems we should switch to using skiplist but how do we go about doing it? Do the > databases need to be converted in some way or do we just shutdown and restart? I haven't yet done it myself. It's documented in doc/install-upgrade.html though (just search for 'skiplist'). I'd back up all the databases somewhere safe first.
