@gusto said in Very slow upload on pfSense in KVM:
Now I need to see if it will be stable.
On a router, LRO, TSO and hardware checksum offload must always be disabled.
These features are good for endpoint devices but not for a router.
There are millions of posts on this forum about this theme:

but even better if you disable it in loader.conf.local, where the other unnecessary functions include EEE, flow control, etc. (so stay protected from FW upgrades)

It's not easy to get it to work well.
You can almost forget about using Suricata and Snort with Realtek.
For me, ESXi and Xen (for web server / VPS) remain eternal love 😉
