Re: [vpp-dev] multi-core multi-threading performance

Hi all, Any help/ideas on how we can have a better performance using multi-cores is appreciated. Thanks, Pragash Vijayaragavan Grad Student at Rochester Institute of Technology email : pxv3...@rit.edu ph : 585 764 4662 On Mon, Nov 6, 2017 at 8:10 AM, Pragash Vijayaragavan

Re: [vpp-dev] multi-core multi-threading performance

Ok now i provisioned 4 rx queues for 4 worker threads and yea all workers are processing traffic, but the lookup rate has dropped, i am getting low packets than when it was 2 workers. I tried configuring 4 tx queues as well, still same problem (low packets received compared to 2 workers).

Just 1, let me change it to 2 may be 3 and get back to you. Thanks, Pragash Vijayaragavan Grad Student at Rochester Institute of Technology email : pxv3...@rit.edu ph : 585 764 4662 On Mon, Nov 6, 2017 at 7:48 AM, Dave Barach (dbarach) wrote: > How many RX queues did you

Re: [vpp-dev] multi-core multi-threading performance

How many RX queues did you provision? One per worker, or no supper... Thanks… Dave From: Pragash Vijayaragavan [mailto:pxv3...@rit.edu] Sent: Monday, November 6, 2017 7:36 AM To: Dave Barach (dbarach) Cc: vpp-dev@lists.fd.io; John Marshall (jwm) ; Neale Ranns

Re: [vpp-dev] multi-core multi-threading performance

Hi Dave, As per your suggestion i tried sending different traffic and i could notice that, 1 worker acts per port (hardware NIC) Is it true that multiple workers cannot work on same port at the same time? Thanks, Pragash Vijayaragavan Grad Student at Rochester Institute of Technology email

Re: [vpp-dev] multi-core multi-threading performance

Have you verified that all of the worker threads are processing traffic? Sufficiently poor RSS statistics could mean - in the limit - that only one worker thread is processing traffic. Thanks… Dave From: Pragash Vijayaragavan [mailto:pxv3...@rit.edu] Sent: Sunday, November 5, 2017 10:03 PM To:

[vpp-dev] multi-core multi-threading performance

Hi , We are measuring performance of ip6 lookup in multi-core multi-worker environments and we don't see good scaling of performance when we keep increasing the number of cores/workers. We are just changing the startup.conf file to create more workers, rx-queues, sock-mem etc. Should we do
