I read the same paper, and concluded that my real problem was that the default of using every possible IRQ to get every CPU involved in network packet work. I had a similar (?) challenge on a Red Hat Enterprise Linux box. I've got the latest kernel version (3.10) on Ubuntu 12.04 with the latest firmware on the NICs.
Qnx 6 com port rclocal msi interrupt driver#
I've looked all over the be2net driver documentation from Emulex, even sent them an email, with no luck. A typical RSS configuration would be to have one receive queue for each CPU if the device supports enough queues, or otherwise at least one for each memory domain, where a memory domain is a set of CPUs that share a particular memory level (L1, L2, NUMA node, etc.). In the bnx2x driver, for instance, this parameter is called num_queues. The driver for a multi-queue capable NIC typically provides a kernel module parameter or specifying the number of hardware queues to configure.
Qnx 6 com port rclocal msi interrupt how to#
I've gotten a hint on how to enable multiple TX queues from Scaling in the Linux Networking Stack: be2net 0000:01:00.1: created 4 RSS queue(s) and 1 default RX queue I think the problem lies in the fact that only one TX queue is used: # dmesg | grep be2net I have checked and yes, I have mq qdiscs, which should yield the highest performance: # ip link list | grep eth3ĥ: eth3: mtu 1500 qdisc mq state UP qlen 1000 In order to improve the TX performance of pktgen, I stumbled across this document: I'm using pktgen with the NST scripts, macvlan interfaces for multiple threads and I only get ~1Mpps, all four cores at 100%. If I increase the packet size and MTU, I can get near line speed (~9.9Gbps). I am testing maximum pps using minimum packet size for UDP and results are miserable compared to these: 2012-lpc-networking-qdisc-fastabend.pdf (sorry, I can post only one link). I've checked the bandwidth of the RAM, which is ~12Gbps, so no bottleneck here. I am testing the network performance of two workstations, each having 2.4GHz Xeon quad core processors and NC550SFP PCIe Dual Port 10GbE Server Adapters, linked back to back.
