This patch introduces caching for OrangeFS server lookups and getattrs. The userspace OrangeFS client has done this in the past. We see a significant (3 to 4 times) performance improvement with these patches at a cost of consistency across the cluster, which OrangeFS doesn't really guarantee anyway.
