[pradeepbbl]

Hey, Thanks for the awesome lib it work great I'm using it in Prometheus custom exporter running the test every 5m so far work great only issue am having is low upload speed as compare to manual run using speedtest.net. Is anyone know hot fix or improve the upload speed.

Thank you, @pradeepbbl. Is multi mode enabled?

I test on ～5Gbps/10Gbps(up/down) cloud server. It almost got the max bandwidth.

hey @r3inbowari sorry for the delay response am making the api call instead using the cli with NThread set to 4, but using cli with --multi also provide similar result

% ./speedtest-go -t 4 --multi  --saving-mode  

    ? speedtest-go v1.6.3 @showwin ?

I guess this is due to the bandwidth limit of the server. When you select 4 servers, their total downlink bandwidth may be less than 300Mbps. You can adjust the connection number(-t 8 or NThread = 8), according to speedtest-cli this number should be 8. And then it will connect to more different servers.
