So you using 1,5 and sp1 gives you 1 Gb max throughput though the unit.   
Depending on packet size etc.    Thats the max per the physical unit can do on 
those ports.  1481 meg is max with 1500 bytes packets, and 860 is max with 512 
bypte packets.

I’m sure you had plenty of users etc.  I would except between 300-500meg max.  
depednign on the packet size, 116meg is 64 byte, so really depends on the 
average packet size at that point.

Subject: [Mikrotik Users] RB2011UiAS Performance Tuning


Had a CCR1009 get blown by lightning today. The only thing I had with an SFP to 
swap in its place was an RB2011UiAS.

Typically running peak of about 500Mbps in traffic in the evenings.

I have disabled the LCD, turned off connection tracking, disabled all mangle 
rules, and disabled as many filter rules as possible without compromising 
security (3 simple port filter rules remain). All services are disabled except 
SSH and Winbox for management. No NAT rules are enabled (some are configured, 
but they are disabled).

BGP is in use with one peer, receiving only a default route by filter (peer 
sends all routes, but I'm filtered for only default).

The only interfaces in use are ether1, ether5 and sfp1. All are routed (no 
switch or bridges configured). Each interface, except sfp1, has one VLAN for 
telemetry management.

I'm still seeing 70-100% cpu usage at only around 150Mbps (13kpps) with nearly 
all traffic falling in to Fast Path on 6.43.16 with the CPU set to 750MHz.

Have I missed any performance tuning options? I just need it to work half way 
decent for the night, I have a new CCR1009 on the way.
