Italiandevil0505 Posted December 15, 2020 Share Posted December 15, 2020 (edited) When I run a speed test to the server I can't get the full 2.5GbE but when I run a file transfer it caps out at 129MB/sec even if I am copying from the cache drive. If I transfer to or from an NVME on the server to the cache drive on the server I get the full speed. My Desktop PC drive has two SSD drives and transfers between them exceed 500MB/sec. I attached some pictures. Any help would be appreciated. Thanks Edited December 17, 2020 by Italiandevil0505 Solved Quote Link to comment
Italiandevil0505 Posted December 16, 2020 Author Share Posted December 16, 2020 Here is the diagnostics log. Any help would be much appreciated. The funny thing is, I remember when I first started testing this out I was getting the full 2.5gb transfer speed. tower-diagnostics-20201215-1852.zip Quote Link to comment
Italiandevil0505 Posted December 16, 2020 Author Share Posted December 16, 2020 So I tried to see if it was maybe just a limit imposed by one file but transferring two at the same time cuts it in half instead of using the whole 2.5gb Quote Link to comment
Italiandevil0505 Posted December 16, 2020 Author Share Posted December 16, 2020 Oddly enough when two computers are accessing the network it saturates the full 2.5gb but either one of them alone does not. All of these have 2.5gb nics on a 2.5gb switch. Quote Link to comment
JorgeB Posted December 16, 2020 Share Posted December 16, 2020 Run an iperf single stream test to check lan bandwidth. Quote Link to comment
Italiandevil0505 Posted December 16, 2020 Author Share Posted December 16, 2020 Hey thanks for the help. Here is the iperf test. Quote Link to comment
JorgeB Posted December 16, 2020 Share Posted December 16, 2020 iperf looks OK, if you haven't yet try copying from a disk share instead of user share. Quote Link to comment

JorgeB Posted December 17, 2020 Share Posted December 17, 2020 By the screenshot I can't tell if that's a disk share or user share, you can name them whatever you want. Quote Link to comment

JorgeB Posted December 17, 2020 Share Posted December 17, 2020 On second though pool names can't have spaces, so that must be a user share, try it on the disk share, you can enable disk shares on Settings -> Global Share Settings Quote Link to comment

The weird thing is, if I do a transfer from two separate computers I can saturate the full 2.5gb link on the server. However, if I do a transfer from just one desktop I am stuck at 129-130MB/sec.

Italiandevil0505 Posted December 17, 2020 Author Share Posted December 17, 2020 Well I think I figured it out. Must be a bug in the new 6.9 beta builds. I forgot I had updated to that. I was on Beta 30, updated all the way to RC1 and had the same issue. Reverted back to 6.8.3 and transfer speeds are flying now. How would I go about reporting this bug? Quote Link to comment

Were you able to figure this out in the latest 6.9 stable releases? Quote Link to comment
