Hi Bob,
<div class="">We were testing it between two similar servers rsynic and copy paste both ways ( read/write) was the same around 300MB/sec average. Of course the speed test on the pools provide higher throughput around 600MB/sec <br class="">

<br class="">
Are these read rates or write rates? Read rates should be able to come close to pool or wire limits. Write rates over NFS are primarily dominated by latency on a per-writer basis.<br class="">
<br class="">
Increasing the MTU to 9k has been shown to improve throughput quite a lot for large transfers.<br class="">
