That doesn't really make sense, though, since Mongrel logs almost
nothing. It shouldn't materially affect performance because it is
almost never writing anything to the file.
If, on the other hand, you accidentally pooled your app logs into the
same file, then yeah, that will create a performance hit under load
because every requests on each different process is trying to push to
that same file and just depending on the OS to sort it out.
