But I'm not sure it would show as a disk bottleneck. If you have
frequent small writes to a disk and each write is delayed while
antivirus checks the datastream for virus signatures, the many tiny
delays could aggegate in to a much bigger file i/o slow down. The
system may experience a higher
You can have conditional access logging.

condition='foo'
If set the Valve will look in the ServletRequest for an attribute called
foo. If it exists then the request is logged. (Of course you

I think a long time ago in a galaxy far, far away I remember something
about antivirus impacting file I/O performance. Would your box happen
to have antivirus enabled? If so, any chance you could exclude your
logs from it and/or disable it for the purpose of a test?

Something seems odd with your system. I have pounded some tomcat
installations with old unix hardware with and without access logging and
could hardly tell the difference.
In linux - i was able to tell more of a difference, but not enough to
turn off logging.
I am at a loss of where the bott

Unless you are max'd on working threads - access logging should not be a
performance hit. Access logging takes pace after the response is sent to
the client.
BUT if the access logs are big, AND you a re low on disk, AND/OR your
disk is SLW then that could be a problem. The overhead of log
from Tomcat -
but I don't know how to evaluate this.
