traffic shaping on bridge interface

hello
i have rb450g, i have connected 100 mb link to ethernet 1 and about 100 clients are connected to other four interface, all ports are bridged, i want to use traffic shaping for all clients.

i have tried this

http://wiki.mikrotik.com/wiki/Basic_traffic_shaping_based_on_layer-7_protocols

but processor loads about 95 %, can anyone suggest me other way?

Thank you

I am having a similar issue with a 450G with a much simpler packet mark and queue. I am using http://wiki.mikrotik.com/wiki/TransparentTrafficShaper

but I only have an smtp and other marks

My rate limits are all set to 15M SMTP, 25M other, 25M Main

CPU is 90% and up once I hit 8Mbps

If I “torch” the interface with a three second timeout, I have about 17000 entries, so there is a lot of small traffic. Is there a better way, maybe lust limit the interface to 25M and, make a different kind of filter for smtp?

I am running v4.6

Thank yuo i will try it

Bridge filtering is very cpu expensive. Try proxy-arp routing instead. Functionally, it will be almost the same as bridging.

“proxy arp routing”?

Let me add a qualifier here. These are public IP’s and I cannot add a hop in between the servers and the public gateway, otherwise I would not be using a bridge.
