Re: [ovs-discuss] Per-flow QoS/rate limiting

2016-03-30 Thread Borasy Kong
Hey Ben, I actually went through and followed the QoS part and implemented the rate limiting on a physical port interface(wlan0). But it seems the rate limiting doesn't work on physical port. It only works on virtual port. Do you know any workaround this problem?? Thanks Borasy On Mon, Mar 28,

Hi I want to test performance and latency with dpdkr ports. In order to do so, I configured 2 such ports, and wrote a test program that lookup for the relevant rings, and streams traffic into the rings. I run this program as a secondary DPDK process. Once I invoke the program, and I enqueuer mbu

[ovs-discuss] IVSHMEM device performance

2016-03-30 Thread Eli Britstein
Hi In a VM, I add a IVSHMEM device, on which the MBUFS mempool resides, and also rings I create. I saw there is a performance penalty if I use such device, instead of hugepages (the VM's hugepages). My VM's memory is *NOT* backed with host's hugepages. The memory behind the IVSHMEM device is a h

Re: [ovs-discuss] IVSHMEM device performance

2016-03-30 Thread Kavanagh, Mark B
Hi Eli, I'm curious as to why you want to use IVSHMEM devices in a setup like this - the whole point of IVSHMEM devices is that the same memory is shared between host and guest, such that mbufs can be passed directly between rings 'zero-copy', thus side-stepping the performance penalties inhere

Hi Mark, Thanks for your reply. Maybe I didn't explain well. Indeed, I use the IVSHMEM with zero-copy methodology. I don't do any packet copying. As such, I don't have any memcpy penalties (as I don't use it). Also, vhost-user device doesn't suit my needs, as I truly want a pure zero-copy system
