So if an object gets written to disk, then subsequently becomes frequently requested, will this compromise performance as the object must now be pulled from disk every time? Following on from that - would a smaller cache_mem, which will allow the OS to perform more disk caching, potentially perform better than a larger (but still sensibly sized) cache_mem?
