I think regardless of whether access logging is on or off by default,
once it is
on (either by default or by configuration), developers expect immediate
updates.

I think we need to do a survey of how useful access logging is during
development,
and how much of a performance penalty people are willing to pay for it.

Tomcat disables it by default, and nobody has ever complained about it.
