I have a Routerboard CRS-125-24G-1S (Gigabit ports) with 6.34.3 routerOS.
My ISP fiber is about bandwith of 200M for down and 100M for up.
The settings are standards and I do not implemented queue type or restriction .
I only have one rule for NAT masquerade .
The navigation works , it’s all right , but all my downloads are limited to exactly 100M even my devices having Gigabit ports.
Does anyone have any idea what might be to help me ? Thanks.
Check actual negotiated speed on the CRS WAN port is 1Gbps, looks like it’s actually 100Mbps (faulty cable?, autonegotiation problem, 100Mbps port on the ISP router…).
Both is 1Gbps. Wan port ISP OTM (fiber) and ether port for my PC.. 1Gbps full duplex.
Any ideas?
Does it happen from a device directly connected to the CRS?
Open a new terminal and issue:
/export hide-sensitive
That will generate an export of your configuration, so that you can post it here.
Additionally, issue:
/system routerboard print
And post it here.
The limitation being exactly 100Mbps seems to indicate an interface speed negotiation problem.
Check wit your ISP support if there’s any upgrade for the router that may include a fix for these, you wouldn’t be the first case…
I configured on a PC x86 the trial version of Mikotik with two gigabit ports , and there was no limitation of bandwidth . My download was 197Mb !!

Can you monitor if CPU rises to 100% while doing a speed test?
If so, try fasttrack, see http://wiki.mikrotik.com/wiki/Manual:Wiki/Fasttrack
CRS is a swicth with a CPU to do some L3 duties and offer more versatility, fasttrack will help it reduce CPU load.
Thanks again for your help!
I monitor without Fasttrack and max usage is 90%
I enable fasttrack and speed test increase to 122Mb : 
and CPU usage average 75%
Latest RC (6.34) channel contains more enhancements for fasttrack/PPPoE, which in your case you will benefit more, make sure you also upgrade firmware once you update ROS, you should be able to reach 200Mbps with lower CPU usage.
