bandwidth test

hello,

i have some questions about this build in bandwidth test from mikrotik.

When i’m doing this test through a GRE tunnel ( TCP connection count = 20) i’m receiving a stable line of 922Mbit avg.
but when i’m sending it keeps flashing between 600-870 Mbit/sec. what gives me a 750Mbit/sec avg. why does sending not give me a straight line?

Check your CPU load. Maybe the device that is generating the test data has reached it’s CPU resource limit.

it’s around 85% most of the time…


and this is my graph :

still not understaning why my graph has those ups and downs..

Dear.

I have a Ccr1009 and I’m trying to set the speed of some cpe and when I set in simple queue it didn’t give me the speed I assigned even connected from the port of the Mk, when I set 10M its just gave me 4 or 5 M. I was wondering if someone could help me?
