Could be local packet loss, which the VPN eliminates.
South Africa’s biggest forum. Discuss, discover, and connect with thousands of members.
It's definitly not a 'me' issue, as the issue would persist when running over a VPN, since the traffic still originates from my line, my switch, my computer. I have no packet loss without a VPN, nor with a VPN so it's certainly not that.what do you get via web client? Web Squad are at Teraco where Google is and I get full speed so the variable is isolated to you.

The VPN eliminates packet loss internationally, so no, it wouldn't persist. That's why CISP setup a local proxy so users with packet loss to band-aid the loss as the loss to local end-points is less punishing for TCP retransmits due to lower latency. Packet loss to EU is significantly more impact than packet loss locally. Test with some iperfs to really see if you have packet loss.
Are there any iperf servers in South Africa? I know seacom killed theirs last year...
Not necessarily internationally only, since a VPN would have their own routes corresponding to DC switch configurations/etc. The ISP routes would be wholly replaced once traffic has been routed from the ISP to the VPN and then the VPN routes it onward.The VPN eliminates packet loss internationally, so no, it wouldn't persist.

Cool, will test now.

Are you just proxying Coolidea's iperf lol?

Anyway the results are much of the same for iperf. Both results are equally as poor, connected over ExpressVPN or not. So I'm coming back to my routing theory lol.
Can't post results, because they are too long lmao, so ghostbin it is!
No VPN

Tests done connected directly to the CPE. RIP packet loss, though I'm not sure how stable CISP's iperf is hahaha, so I'll put it down to that, given how the UK iperf is stable...
Though packet loss wouldn't explain why ExpressVPN routes with no issue in any event, since the traffic still egresses over my vuma line.

Since this is directly over the CPE, how the hell is it fixed? Networking was one of those units I didn't particularly enjoy at University... The thing I don't get is that packet loss would affect my download as well, but that is fine.
Also tried different cables from PC to CPE (cat 5e, cat 6 and cat 7) and different ports, same results. Also tried on my desktop and laptop for good measure, same results.
