Gigabit network. Unable to get faster than 30MB/sec

macguru42 · 15. Dezember 2021

Hi all,

I've looked all over for a solution, but it has eluded me.

HP N54L microserver 12GB mem 2.2Ghz CPU

OMV 5.6.20-1

Gigabit network / switch / OMV connecting at 1000 Full.

I have onboard 6 disk SATA setup as RAID10, so the storage is fast enough...

When I copy to or from either my ESXI server or my computer the max transfer is 30MB/sec .. sometimes I get 40MB at a burst..

Now theoretical max on Gbit is 120MB, but of course with overheads I expect less, but 80+ would be really nice / useful.

HELP!

Check your hardware. Switches, cables ...

macguru42 · 15. Dezember 2021

thanks for the speed reply.. the switch shows all connections are Gbit. OMV shows Gbit. ESxi shows Gbit..

I've done some digging and things are... a bit ... odd..

when I run:

Code

ip a

I get the interface as:

enp3s0

but in OMV its listed as

enp2s0

attempting to change this brings a whole load of errors:

Code

I have the feeling at some point I may have mangled my OMV...

Options here are...

1) wipe OMV - re-install.. I've only got two RAID arrays setup and from what I remember they will be recognised, so just re setup SMB / NFS shares

2) someone looks at this and says "I know how to fix this.. just do <foo bar> "

thanks again for the assist..

See: https://stackoverflow.com/questions/68802802/repository-http-security-debian-org-debian-security-buster-updates-inrelease

sudo apt-get --allow-releaseinfo-change update

Then check the network speed with iperf3 and post the results to fix speed problems

This will tell us, if it is the network or someting else.

Hi Zoki,

Thanks for taking the time to help out.. applied the apt-get and setup iperf3 output:

which is ... slow.. considering everything is showing Gbit as the connection...

what's next to try ?

Zoki · 15. Dezember 2021

Do you have another VM in the ESXi? Try iperf3 with this one.

Do you have other devices in the network to test?Idea is to rule out single components.

I would do a test without the ESXi first.

macguru42 · 15. Dezember 2021

Hi,

that was a test from an i5 Mac 11.6.2 to OVM

Sorry if I wasn't clear.

My SMB / NFS tests were from / to:

i5 macOS 11.x

i7 Mac Mini ( running esxi 7.x )

M1 / iX new Macs with Gbit adaptor

The iperf test was from i5 macOS to OMV

No VMs were harmed in this test (so far)

Thanks again..

Take a very hard look at the ethernet cable you are using and if you have one you can swap try that.

Zoki · 16. Dezember 2021

Given the number of devices you have at your hands, you could try to find a pair with acceptable transfer speed and exchange the cable / switch port between one of the pair and your OMV server.

macguru42 · 16. Dezember 2021

great suggestion..

and..

I fixed it...

And it wasn't OMV.. tested from other devices and getting 100MB+

And the issue was....

Sophos AV

removed and getting 80MB+

Quite unbelievable that its that inefficient that it cripples the network connection..

Now off to find a reliable AV for macOS...
