Re: big problem with HTB/CBQ and CPU for more than 1.700 customers

As i told before, i tryed to shape my traffic CBQ and i did use u32 filters. the results were exactly the same as HTB using u32 filters (i tryed before too) or not.

 

Do you have in your HTB setup a class per customer? I’ve seen different setups, but all of them shaping the traffic either based in protocols or/and IP ranges (it isn’t our reality whilst we have at least a class per each single IP within the network).

 

After some readings, i’m starting to suspect about my NIC driver (e1000). Do you have in your Dell PE 1850 interfaces using the e1000 driver? Is the entire traffic passing by this server? I suppose that problem is something about the hardware or software interruptions. Are you using the default parameters for the e1000 kernel module?
