Where are you sending your logs? Mine all go to local files, and I've had
no need for log_fifo_size, which seems to be applicable to forwarding
to other syslog-ng servers over TCP. Are you forwarding log entries
to a remote server via TCP? On mail servers I only log to local files
(rotated hourly) and collect these out of band (after local compression).

I thought that output queue overflow leads to dropped messages, not
blocking, but I could be wrong about that. Are you sure that a lower
value causes performance issues rather than perhaps lost messages?
