I've poked around logging a bit, and here is what I discovered.
Writing to a File instance in JRuby is actually not too bad, until you
set sync = true on that instance. With that, MRI writes 7 times slower
(which is still fast enough), but JRuby does it 1000 times slower.
I noticed that the other day when someone mentioned log issues on irc.
Great minds ;-)
Looking at <http://www.ruby-doc.org/core/classes/IO.html#M002287> I
think I've got sync wrong. I assumed it was fsync, but it just means
don't buffer writes.
Commenting out channel.force(false) in IOHandlerSeekable#sync feels
correct, and speeds up writes enormously. Does that look right?
It seems good. Works for me. =)
