Slow upload with pfSense (download is ok)

[paulvanduijn]

Good afternoon pfSense forum users,

My problem is the following:

My download is fine, but the problem is the 1 MB upload.
If I access my NAS outside my network and want to download a file, I get the speed of 1 MB.

The configuration is as follows:
ODIDO fiber optic 1000/1000
Protectli VP4630 – 6 Port Intel i3 with 6x Intel I225-V Rev. B3 2.5G Ethernet, RJ-45.
With pfSense 2.7.2-RELEASE (amd64) installed
It is a standard installation, no packages installed.

Have used different options (Synology Quickconnect and Tailscale installed on the Synology).
Can someone help me increase the upload to the speed you would expect with a 1000/1000 fiber optic connection.

Thanks in advance for the help.
Yours sincerely,
Paul

@paulvanduijn I have the exact same problem on two pfSense VMs running in KVM with VirtIO drivers. So far I cannot find a solution online. I tried to Disable hardware checksum offload and Disable hardware TCP segmentation offload and it did NOT work. My download speed is 500-600 Mbits but upload speed is 0.1 Mbit.

This happens on the latest pfSense 2.7.2 and pfSense Plus 23.09.1
