It is, and unless you stop and start the daemon a lot, that's probably better than what you're doing at the moment. Also once you've transferred the mfs memory to squid, you *may* be able to add a real disk cache because of the reduced load on the disk. I'd try starting with a small diskd cache just to see if ffs can cope with the base load of objects evicted from the memory cache.
