trohn_javolta Posted December 31, 2018 Posted December 31, 2018 Ok, so after PHP issues I started off with a fresh armbian install and via armbian-config I installed OMV 4. Install finished without any problems but if I copy stuff via smb the tranfer speed is really bad and I don't know why. On an old install with OMV 3 I used to get nice 100 mb/s. The cpu temp also used to be at like 80 °C during copy, now it looks like this: Following extra options are set in smb.conf: min receivefile size = 16384 write cache size = 524288 getwd cache = yes socket options = TCP_NODELAY IPTOS_LOWDELAY I also checked smbd app, it's running on a big core.... I get the feeling that not all the avaiable resources of my HC2 are used anymore. Can anyone help me here? The reason number 1 for choosing armbian + OMV were the introduced tweaks that got me NAS-like tranfer speeds... Other os' I tried all have equally bad tranfer speeds. I wish everyone reading this a Happy New Year 2019!

One core goes to 50% ... like nothing is happening.

I never checked this, I thought I have plenty ram left. Comparing to older setup all I added to the mix is docker + some small containers based on alpine linux. And wow.. that one mono app needs lots of ram: Edit: Ok, now I disabled mono app and also saw that a python app uses quite a bit of cpu, also disabled that and get around 70 mb/s. Can't I somehow tell samba to "overrule" all other apps, so I get my 100 mb/s when I need them? I don't copy stuff back and forth all the time, but when I do, full gigabit speed would be nice.

Stupid question: With reading you mean copying from hc2 to local machine, right? That's what I keep testing. I could lower ram usage a lot, sth. is messed up with my jackett (mono) container. But even disabling the container I cannot get more than like 60mb/s max.... I now check with htop, I think it's nice to check processes. During copy via smb I see that all the big cores are pretty maxed out..at least htop shows that. Still cpu temp isn't as high as it ways some months back when I used to get my 100mb/s. I'm thinking about overclocking the hc2 xD Idk if that may help..what do you think. Since I used to get these "high temps" like up to 85 °C I had the plan to add better cooling some time ago. I mainly was worried about the hdd temp being too high for my taste, I think like 50 °C. So now I finally added active cooling and with that I think I could overclock the hc2 It's not very professional But it works. Took this fan kit, cut off a bit from the metal frame and added feet.
