[OPN-20071-R]

For testing, set MSS on LAN interface to 1300, then test again and watch CPU and RAM while testing.

When MSS is set to 1300 on the LAN interface, the CPU and ram usage is indeed lower, but it does not result in a speed gain. See speed tests below.

OPN-20071-R


Sitecom WLR-4004

The machine will be maybe 6 years old indeed. @mimugmail I will try it today!

CPU: Intel(R) Atom(TM) CPU Z530 @ 1.60GHz (2 cores) unfortunately only 32bit
MTU/MSS are still at the default setting.
All settings are still on default after installation, so no IPS?

Hello,

Recently I switched to OPNsense. I was able to buy a second-hand Deciso OPN-20071-R to replace my old Sitecom router. On the OPN-20071-R I installed a clean version of OPNsense-19.1-OpenSSL serial-i386. On the sitecom I always reached a speed of 150/150 Mbps but after switching to OPNsense I only reach a speed of about 55/80 Mbps. Have I forgotten something somewhere? Or can't the Intel Atom Z530 handle higher speeds? Isn't it strange that a cheap Sitecom router can reach my full internet speed and not this OPNsense box?
