Slow internet speed

[imthiazaar]

Hi,

I am facing extreme slowness in internet browsing and speed test.

My setup is as below.

Intel i7, 2 * 25Gpbs NIC, 16Gbps RAM 256 SSD, PVE(pve-manager/7.1-7/df5740ad), Deco X60 router as access point.

Internet <> Modem <> PVE <> Sophos XGFW <> Deco X60 Access Point mode(3 * Deco X60 in Mesh) <> Devices( phones, ipad, apple tv).


I have installed Sophos Firewall as Internet Gateway with Deco Router. Speed test results are 10mbps now.

Previously before the PVE setup, speed result results was 500mbps. Below is my earlier setup.

Internet <> Modem <> Deco X60 in Router mode (3 * Deco X60 in Mesh) <> Devices( phones, ipad, apple tv).

Please suggest on improving the speed.

Hey,

on what device did you run the speed test? And how did you test the speed? If not done on PVE, run the speedtest there. Could you also test the speed between PVE and some device with iperf3(AFAIK there is a portable version of it for windows[1], if you have linux on the device, iperf3 should be available on basically every distro).

on PVE:
iperf3 -s

on client:
iperf3 -c <PVE_IP>

The setup looks fine, the first step has to be figuring out where in your setup the speed reduction happens. After installing speedtest-cli on PVE you can run speedtest. Could you post the result?

You did not mention how and where you ran the speed test in your original post, without this kind of information it is really hard to guess what might be the problem.

Attached the o/p. This looks good. But in my setup Sophos is the gateway between all endpoint devices.

Is Sophos XGFW a VM? What is Sophos setup to do, is it possible internal traffic is treated differently than other traffic? could you post the output of ip a, ip r and cat /etc/network/interfaces.
