I don't have any of the configurations addressed by Brian: > Your server vol file isn't perfect for large rsync operations. The changes I'm recommending will improve your rsync performance if you are moving a lot of small files. Please backup the current file before making any changes. You should comment out "readahead" and "iocache". In the quickread section change the "option cache-timeout" to 10 and change the "max-file-size" to the size of the largest file of which you have many, rounded up to the nearest factor of 4. > After you have made the changes across all the storage nodes please restart Gluster and measure the throughput again. Do you have any examples or ideas how I can tweak it more? should I add more options? Kind regards, Michiel
