jang430 Posted September 2, 2020 Share Posted September 2, 2020 Seems I may have a network problem. Don't know if it's a switch thing, NIC thing, or cat5e thing Is there any tool to put on Unraid for me to do some testing? I'm having some problems in Parsec gaming. From logs, it shows my network, though wired, is not performing well consistently. My transfer from NAS to Desktop has never been very fast as well. I always suspected this, but never had any motivation to fix it, so as long as I can access and stream shows from NAS fine. But now, I'm using Parsec, I think there's no room for lag. I want to fix the problem, if there's any. Any suggestions? Quote Link to comment

Is this good enough? Could this possibly change over time? As I don't know when gaming via Parsec, the performance is as good. Edited September 3, 2020 by jang430 Quote Link to comment
JorgeB Posted September 3, 2020 Share Posted September 3, 2020 For testing you should use a single stream, and if all is working correctly it still should give close to line speed. Quote Link to comment

JorgeB Posted September 3, 2020 Share Posted September 3, 2020 That's low, with gigabit you should easily get line speed, or very close to that, try differente NICs/cables/switch Quote Link to comment
jang430 Posted September 3, 2020 Author Share Posted September 3, 2020 Can I plug direct wire between NUC and NAS? I've re-used old Cat5e IO, maybe that could be one of the reasons? Quote Link to comment

Now, I don't know whether to be happy or not I now know more or less where to start troubleshooting. Either it's the switch, or the internal wiring between walls, or the old Cat5e IOs that I reused.

jang430 Posted September 3, 2020 Author Share Posted September 3, 2020 @JorgeB, when I was testing earlier with the very bad results, I was downloading via torrent 8 MBps. Does that affect my testing via iperf? Today, nothings downloading, the following are the results. https://pastebin.com/6UssYse9 Quote Link to comment

JorgeB Posted September 4, 2020 Share Posted September 4, 2020 I usually test with the server not doing anything so there's no interference in the test. Quote Link to comment
