Description

ixgbe NICs with SFP ports attempt to read the modules and wait for 1s when queried by ifconfig -v.

This means that loading the dashboard with the interfaces widget or the Interfaces Status page is delayed by 1s per interface.

For example:

ix0 has an SFP+ port on the 8200. ix2 is a combo port.

Specifically:

It's a driver bug...

They fixed it a year ago in OPNsense. Is it fixed in pfSense Plus 23.01 and/or FreeBSD 14-Current?

Seems that it still tries to detect it 10 times:

Here is why dashboard is slow:
