Following my problem regarding the speed of a wireless connection between 2 RB133 I already posted on the forum, I’ve made some testing on the overall performances and bandwith availability of RB133.
The testing scenario includes 2 notebooks, a well running wired network with Cisco switches, a well running wireless network with Cisco AP1131, both the RB133 and the bandwidth tool from Mikrotic (both the stand-alone btest.exe tool and the WinBox included tool).
All the tests were made using udp packets.
First of all I tested the bandwidth between the two notebooks directly connected by a crossed cable using btest.exe getting a result of 97Mbps on the 100Mbps ether interface link.
Then I run the the btest.exe between the notebook and the ethernet interface of the RB133 getting NO MORE than 55 Mbps! Of course I’ve got same result on both the RB133 units.
Next step was running the WinBox tool internally to the RB133 testing both the Ether1 and Wlan1 interfaces. This should load just the internal bus and the TCP/IP stack of the board. Well, also here I’ve got NO MORE than 50Mbps on both the interface.
Last I retested the Wireless link between the 2 boards using as simple as possible wireless configuration (AP to Station, no compression, no NSTREM, no Crypto) getting same results as early: no more than 14Mbps on 811A and just a little better on 811G
Just for fun, I tested also the BDW between the notebooks through the 811G Cisco link getting more than 35 Mbps.
Hope some one can help me understanding this unexpected lack in performance and how to get the link speed MikroTik promise.
