Can't get more than 5 meg in either direction using PCQ on R

Hardware MikroTik hardware general

Hello everybody,

On my RB532 I have set up PCQ such that everyone who connects through the device should share 12M down and 8M up equally. The problem I’m having is that for whatever reason, I can’t get the unit to pass more than 5 meg down (6-6.5 meg if you include uploads). This is consistent no matter how many session I have flowing through the bridge. Has anyone run into this before? Thanks in advance!

Do you use wireless (which standard 802.11 a, b, g) or Ethernet ?
Make sure troughput is not limited by upstream provided as well.
Do you have any other queues ?

This is purely an ethernet bridge. I have no other queues. When I turn off the PCQ, I can push 37-39 meg through the bridge, so there aren’t any problems with my test environment, so I don’t think there are any issues there.

post your queue config here - do you have any max-limit AND limit-at values set anywhere?

My goal is to have everything except for one ip address share the PCQ queue such that bandwidth gets evenly distributed among them. For testing purposes, I haven't enabled the Office rule, but it's irrelevant anyway. Thanks!

hmmm… strange that… tried this config with all ports bridged, and it seems to work fine…

what does your routing config look like?

I’m not doing any routing with this device, as I wish it to be just a transparent bridge, but here it is:

/ routing ospf
set router-id=0.0.0.0 distribute-default=never redistribute-connected=no redistribute-static=no
redistribute-rip=no redistribute-bgp=no metric-default=1 metric-connected=20 metric-static=20 metric-rip=20
metric-bgp=20
/ routing ospf area
set backbone area-id=0.0.0.0 type=default translator-role=translate-candidate authentication=none
prefix-list-import=“” prefix-list-export=“” disabled=no
/ routing bgp
set enabled=no as=1 router-id=0.0.0.0 redistribute-static=no redistribute-connected=no redistribute-rip=no
redistribute-ospf=no
/ routing rip
set redistribute-static=no redistribute-connected=no redistribute-ospf=no redistribute-bgp=no metric-static=1
metric-connected=1 metric-ospf=1 metric-bgp=1 update-timer=30s timeout-timer=3m garbage-timer=2m

Thanks again for the help, btw!
