So after lots of different advice it turns out that the reporting on the F5 is at fault. Even though the RAM CACHE reports 0 files in the cache and 0 files in the cache, it has actually cached it. This behaviour was checked by F5 and WestCon support and shown through wireshark that in fact the data is in the cache and being served from the RAM CACHE. This could be a unique feature of 10.2.3 F5 and WestCon are yet to prescribe a fix or resolution to this problem. In the meantime we have scheduled downtime for an upgrade to the latest 11 version. Many thanks to all who helped.
