Adam Kocoloski commented on COUCHDB-1054:
-----------------------------------------
Hi Volker, Filipe was only addressing whether the timestamp should be inserted
by the client process or by the logger itself. If done by the client process
it's possible that timestamps may not monotonically increase. We'll certainly
continue to insert timestamps in the log files.
> Better couch_log performance

> Building the messages to write to the console and the log file can be done
> outside the couch_log gen_event. This significantly increases the parallelism
> when many processes log messages. The following relaximation test graph shows
> a throughput increase using the attached patch against current trunk:
