not getting 2.5Gbps speeds, Realtek 2.5GBase-T NIC

[kwisatzjim]

Hi

I installed a TRENDnet 2.5GBase-T NIC that uses the Realtek 8125 chipset for the LAN connection on my OPNsense box.  Installed the os-realtek-re driver.

It connects to a TRENDnet 2.5G PoE switch that is connected to my Engenius WAP that has a 2.5G WAN port, and also to a laptop with a 2.5G USB NIC.

iperf3 shows proper 2.5G speeds between the laptop and the WAP, but going to the OPNsense box is only about 650Mbps.

Is there something I need to do to get the OPNsense box to get the 2.5G speeds? or is this an issue with Realtek devices?

Any ideas?  thanks!

I finally found Intel 2.5G NICs and swapped for the Realtek NIC.  Getting slightly better speed but still not near 2.5G.

after going through all the settings one by one I finally figured it out.  When IPS/IDS is turned on, the speeds drop.  Turn it off and speeds are as they should be.  IDS drops it a bit, IPS drops it a lot more.  IPS with hyperscan drops it the most, IPS with default pattern matcher drops less than with hyperscan.
