Joining a new room is extremely slow
When I join a new room, biboumi seems to be churning its database, I can see a lot of pread64() syscalls in strace, on the sqlite file.
I guess it is searching for logs to send me, but since I have a lot of logs it takes long until it looked everywhere to not find any.
A solution would potentially involve adding an index so the query can finish much faster.
