Hi all, after updating my two instances (my university's build server and PMBS) here is my first impression: The update went more or less smooth. + with 2.5.1 the db update runs through without any error - thank you, Adrian! - README.UPDATERS still has the task to db:migrate the webui DB, which does not exist anymore (bee github #650) - the search in the web frontend does not work, thinking sphinx seems not being able to talk to the database - the system is catastrophically slow, and I mean "slow" with a capital "S"! Compared with the performance of 2.4.6 it seems to need the triple amount of CPU, and four times disk IO - these data come from PMBS. Is there someone, who has tried to downgrade to 2.4.6 again, and is this possible at all, apart from replaying a backup?
