So affects all shared caches, not just the one rock dir. The shared memory page size should be eventually configurable, of course. However, I doubt the fixed page size will always remain the maximum cachable object size in shared-caching SMP setups. Eventually, Squid will use fixed-size shared pages to store arbitrary-size objects, in memory and on disk. I am not aware of any active development in this area, but I am sure somebody is working on it or will eventually work on it because caching large files is important to many. HTH, Alex.
