Hi Folks, Hope to humbly ask for some advice if this list is still active. I’m supporting a legacy product and looking to improve networking performance. It is a PPC460GT used as a bridge device with an ethernet 1Gb (marvell), that routes packets to a pci network card (using igb). Going in the pci interface and out tx to the network, we get a nominal 700Mb, however…
RX - to the marvell we see two things: 1. 300Mbps 2. sys = 100% Any ideas? I’m suspicious that packets are not being handled at a low level and getting copied through iptables rules to userspace. Maybe there is a way to enable DMA to the benefit of incoming packets? Linux mbu-100 2.6.33.1 #245 Fri Nov 1 17:41:21 PDT 2013 ppc GNU/Linux Glacier Thanks! Bill
