Just like the previous poster if i plug my laptop into the modem i get speeds approaching 1 Gbps. When i run through OPNSENSE and plug directly into the LAN port it appears that OPNSENSE throttles the speeds to no more than 360 Gbps.
I've edited the LAN MSS with 1400 as recommended....but no changes.
Nothing special with OPNSENSE - Just a fresh install with the WAN and LAN ports. No NAT, proxies, etc.
In testing I've tired a few other firewall packages (I hate them) but wanted to see if i was dealing with a hardware issue. I've installed PFSENSE and have the same issues....throughput is throttled to about 360 Gbps.
However, i've installed IPFIRE - using the exact same hardware configuration and SURPRISE! I'm able to achieve almost 1 Gbps throughput.
I'm confident this is some type of configuration setting......I love OPNSENSE but need to get this figured out.
Any help would be appreciated!!
I've had similar results. I"m using AT&T 1gb Fiber, and recently switched from Untangle to OPNsense. With Untangle I was regularly getting ~700 down, and ~900 up. With OPNsense I'm getting ~350 down, and ~200 up.
I've tried clamping MSS to 1400, which seemed to slow it down slightly. Then as someone else suggested I did a test with multiple streams, setting both upload and download to 8 streams, which was even worse at ~130 down and ~140 up (combined).
I"m not really sure where to go from here.
