Hi, to have good performance with ceph, they are 2 boosts possible: Maybe we could add them as command option in ceph init ?
1)disabling cephx auth. [global] auth_cluster_required = none auth_service_required = none auth_client_required = none - I always disabling them on my cluster, it's give me around 20% extra boost on 4k iops. and don't require to put the key in /etc/pve/priv/ceph/. I running all my cluster like this since years. Of course, for security, user need to have their ceph cluster on a private network. 2) disable debug log, give me another 15-20% extra boost [global] debug asok = 0/0 debug auth = 0/0 debug buffer = 0/0 debug client = 0/0 debug context = 0/0 debug crush = 0/0 debug filer = 0/0 debug filestore = 0/0 debug finisher = 0/0 debug heartbeatmap = 0/0 debug journal = 0/0 debug journaler = 0/0 debug lockdep = 0/0 debug mds = 0/0 debug mds balancer = 0/0 debug mds locker = 0/0 debug mds log = 0/0 debug mds log expire = 0/0 debug mds migrator = 0/0 debug mon = 0/0 debug monc = 0/0 debug ms = 0/0 debug objclass = 0/0 debug objectcacher = 0/0 debug objecter = 0/0 debug optracker = 0/0 debug osd = 0/0 debug paxos = 0/0 debug perfcounter = 0/0 debug rados = 0/0 debug rbd = 0/0 debug rgw = 0/0 debug throttle = 0/0 debug timer = 0/0 debug tp = 0/0 _______________________________________________ pve-devel mailing list pve-devel@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
