I have classes configured by protocol..
My NIC is the e1000 too (default parameters), but I'm using off-board
cards (with scalable i/o support - good for multi-core setups). The
main problem I had was the number of interruptions (~ 10.000/s)...
With IRQ balance activated, each NIC got used with a specific
processor core, and the use of CPU on these cores was always 100%.
I've solved this problem in my setup (2 Quad-Cores), deactivating the
IRQ balance, that caused the interruptions to be processed by all the
8 cores.
Are you doing p2p control on this server? This is usually what takes
more CPU usage..

As i told before, i tryed to shape my traffic CBQ and i did use u32

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?
