RB2011UiAS-2HnD-IN CPU bottleneck
Hm as I see it right there will be more then one point that is not really matching in
this story here, sorry.
At first the RB2011UiAS-2HnD-IN is a home router with good capabilities and options
but how more a device gets to do, it would be even slowing down the entire power
from the cpu step-by-step, and if enough things come together or on top it would not
really matching the expected power of this device.
- The RB2011 brings wire speed on both lan ports the GB and fast ethernet ports
make a test with iPerf or netIO and you will see it with your own eyes!
Because the speedtest of the provider At&T is not the real thing you should trust on!
What is if 5.000.000 users where doing the test at the same time on a busy hour?
So I really thing this could not be the real thing to test an internet account, sorry.
- SPI = netfilter and NAT = network address translation will even take something
around like 3% - 8% of the total WAN throughput.
- On your side at home you have one router (MikroTik RB) and only for your
own equipment at home. But on the ISP site their are perhaps hundreds till
thousands of internet clients that must be sharing this device at the ISP site
and the same second!!!!! And if there are less users you will be having other
results in my eyes.
- Having in front of the MikroTik RouterBoard a plain modem and not a router
will be also a hint to get better result.
So if this is not really bringing you the expected results it would be better to
split all the entire jobs by using more then one device and all is running faster.
A router for the WAN - LAN routing and one or two WLAN APs for the entire WLAN jobs.
Or plain one big device that is able to deliver the speed that is needed.
