Any news to this tread? We seem to have same sort of issue.
Even between two CCR's (CCR1016-12G) with a 30cm Cat-6 cable we can't stransport more than 250-300Mbps tcp from one side to the other. cpu's on both end are not reaching 100%. (although their is a big difference. One bandwith test on 'send' creates 80% cpu where it the same test is done from the other end we only have 30% cpu. Speed though is almost the same?
Anyway, the bottom line is, we have been playing with some interface queue settings (hard ware queue, ethernet-default, we even changed some pfifo settings) but it hardly seems to make any differences.
We are connected to a 300Mb simmetric line for internet but only in opening multiple connections to ftp servers we can reach 285bps download speeds.
Upload on the other end only nees one www.speedtest
and bang, 298Mbps upload. (Download hardly reaches 200Mbps in total traffic. That means the test + the normal clients traffic...)
So are there problems with Mikrotik to get the speeds we want.
(We also have many clients complaining their speedtest only show 2, 5 or 10 mbps max where their queues are set to at least 20 and with the MT bandwidht test from the CPE's we have no issue to push up to near max. 20Mbs tcp from our gateway router to the clients.)
Everywhere we have hardware queues set as default.
