...ked at nfs-ganesha. But in terms of upper bounds for throughput tests: data needs to flow over the client->nfs-server link, and then, depending on which servers the file is located on, either 1x (if the nfs-ganesha node is also hosting one copy of the file, and neglecting arbiter) or 2x over the s2s link. With 1Gbps links, that means an upper bound between 125 MB/s and 62.5 MB/s, in the steady state, unless I miscalculated. -- Manoj > > * I had the 'cluster.optimize-lookup' option enabled but ran into all > sorts of issues where ls is showing either the wrong files (content...

...nfs-ganesha performance. I've put some SSD's in each brick and have them configured as lvmcache to the bricks. This setup only increases throughput once the data is on the ssd and not for just-written data. Regards, Rik [1] 4 servers with 2 1Gbit nics (one for the client traffic, one for s2s traffic with jumbo frames enabled). Each server has two disks (bricks). [2] ioping from the nfs client shows the following latencies: min/avg/max/mdev = 695.2 us / 2.17 ms / 7.05 ms / 1.92 ms ping rtt from client to nfs-ganesha server: rtt min/avg/max/mdev = 0.106/1.551/6.195/2.098 ms ioping on...

...o be allowed to use that port. An app that wants "any" port (specifies a port number of Zero) will *not* get one in the range of 32xxx. The lower bound of 49152 was chosen to be far away from some other hard-coded apps that I'm aware of and use, including projects such as P2P-Radio, S2S (these two are at Sourceforge also), PeerCast, and others, in case you'd like to try p2p-style radio netcasting to save bandwidth costs. To learn what hard-coded port-numbers your apps use, read the docs for every clue including what's used to talk to the YPs etc. There is a reason for on...
