MikroTik router RB2011UIAS-2HND-IN to slow

My MikroTik router RB2011UIAS-2HND-IN barely manages 400Mbit/s on a 1GBit/s line over ethernet cable. Today I had installed a Firtzbox router for comparison. This creates almost 1000Mbit/s.
Are there any configurations that could be changed to achieve similar results? Is this limitation normal for this model series?

Many thanks, starcow

Do you have fasttrack configured?
Also.. The RB2011 is not the fastest router anymore.. Consider upgrading to a 4011 or 5009.

I don’t know that. What is fasttrack and where can I turn it on?

Cheers, starcow
