@Haioken Hello again.
In which case could you update the relevant forum thread on this find as otherwise there is a ‘wake’ of issues apparently attributed to Rockstor (as the usual default) where as if a thread is updated then others can more easily be informed contextually. I.e on the possible effects if they make the same mistakes. Also it helps to see where we might improve the user experience to help avoid easily made mistakes: ie where the UI could guard / warn guard such actions for example. Thanks for the rich feedback by the way.
It would be easier to track down the cause if you game more info and eliminated extraneous issues such as wifi which can easily vary over time etc. There have been no other (unresolved) reports of general network speed issues and a good way of testing the base performance ie what the IP layer can do is covered in the following thread where @kupan787 and myself share iperf results; in that case it concerns bonded interfaces but the same tool might help with narrowing down the issue (ie ruling out network drivers etc):
In those tests we both, in the end, managed expected dual gigabit saturation.
Another post/thread of interest has details of network card performance differences which may also be of interest:
On a related side note I don’t think it is necessary (in this forum at least) to be alarmist with your post title. There are, as far as I know, no known network performance issues, outside of torrent downloaders, that affect Rockstor as we are essentially CenOS with a much newer kernel. I initially suspected that your NZBGet issue was down to insufficient port access (suspected in another torrent rockon) but from the looks of it that rock-on uses --net=host:
so should have whatever network access it desires. As for the smb protocol stream it would help to know in what context your performance was measured as then others with more knowledge of such things (than me) would be empowered to assist: ie which rockon or service was managing the streaming?
Also you may find the following thread of interest:
So it may be of use to also test plain samba performance to help to narrow things down a little more.
Hope that helps and thanks again for the feedback. Lets hope the forum can get to the bottom of this one:
understood.
