Increasing -cb is pretty cheap; IIRC it's about 32 bytes of memory per
callback, and the runtime overhead only comes into play at shutdown.
My draft change to auto-tune fileserver parameters for a target memory
footprint at https://gerrit.openafs.org/#/c/11629/ just uses all the
remaining memory footprint after the other parameters are tuned for
callbacks. The openafs servers are very bad at making full use of the
hardware resources available; increasing callbacks is one way to make a
more effective use of resources.
P.S. if anyone wants to review and/or test that gerrit change, that would
