Dear gluster experts, I search through glusterfs 3.3 source tree and can't find any fuse open option FOPEN_KEEP_CACHE related code. Does this mean that glusterfs 3.3 doen't support fuse keep cache feature? However I did find keep cache code in mainline. My question is: 1 does glusterfs 3.3 support page cache? 2 if not what is the best practice to improve performance if a file is frequently accessed by read especially through random access fops. 3 does glusterfs 3.4 support page cache, if supported how to enable it through mount option? Thank you very much. -- ???
