Description

in class.tslib_feuserrauth.php:fetchSessionData() is a query to delete outdated data, with a WHERE condition on `tstamp` which has no index - at least for the system i am observing right now - this takes 1.3 seconds on average (executed 10k times on 24h) - way too long

is there any reason why there is no index on `tstamp`?
