Who else has been doing performance testing on the RB260GS... ?

F.

What's the point? It is a hardware switch. 99.9% of them offer linerate performance in layer2 configurations.

Here is my RB260Gs Performance Analysis conducted on May 24 2013.

Tools: Exfo Packetblazer & BV10

Reference performance:

1500 octets frames
82237 frame per second
Frame Loss = 0%

4000 octets frames
31045 frames per second,
Frame Loss = 0%

9000 octets frames
13858, frames per second,
Frame Loss = 0%

With RB260GS inline between Exfo Packetblazer and Exfo BV10.

96 octets frames
1071685 frames per secon
Frame loss = 0.4%

1500 octet frames
81212 frame per second
Frame Loss = 1,2%

4000 octets frames
30222 frames per second
Frame Loss = 2,7%

9000 octets frames
13062 frames per second
Frame Loss = 5,7%

I'm concerned with the high percentage of frame losses ... 1,2% frame loss on 1500 octet frames seems pretty high.

Is there any capability for Mikrotik to improve this ?
