upload speed really slow

[Goddard]

I'm running Pfsense to manage my network and upload speeds appear to be cut in half, but download speeds are great... I am using a bridge with virtio. Any suggestions?

Thanks

Compared to what? Can you give specific numbers?

 

[Goddard]

Rather then 5Mbps it is 1.7Mbps...and I know it is reproducable because I can unplug the wan device and use another dedicated device and it is back to normal.

Do you get normal upload speed with pfsense disabled? Did you configure it to monitor outgoing traffic?

also did you see

?

especially the virtio-net notes to disable hardware checksum offload

That did the trick. Thanks a lot. I actually saw this in the docs when I was reading about how to properly install and it was already checked, but I unchecked it thinking it was something I needed to manually toggle. I guess Pfsense already picked up on the fact, or it is disabled by default?

maybe newer pfsense installations do this automatically, last time i installed it, i had to do it manually

THANKS! This helped me too. I totally missed "IMPORTANT: Enter the web GUI and go in System > Advanced > Networking and flag Disable hardware checksum offload. " but fixed it now and speed is great
