Hi, I did some testing on the performance of CacheFS with NFS by copying a whole bunch of files from the NFS server to a client. Without CacheFS on, it took around 70 secs. However, with CacheFS on, it took around 147 seconds!! An entry in 2005 stated that CacheFS suffered from the fragmentation problem. I wondered if that's the problem....... I am using kernel 2.6.17 with cachefilesd 0.3. Derek
