Did you ever do the performance test without NFS? ex: download directly or iperf..
No, I didn't but since you mentioned it, I ran some iperf tests too. With kernel 4.18.15 the receive and transmit speeds were pretty constant at 112 MB/s every time for the duration of the test (I did several runs). With kernel 4.19.11 the results were a bit more interesting. Usually the receive speed would crawl somewhere around 12-14 MB/s for several seconds and then suddenly jump up to 112 MB/s and stay there, sometimes until the end of the test, and sometimes it would drop back to 12-14 MB/s after couple of seconds. Results attached. -- You are receiving this mail because: You are on the CC list for the bug.
