Re: [vpp-dev] 128k performance is not good as kTCP #vpp #mellanox

Hi Sejun, I’ve never tried spdk, so I can’t know for sure where the issue lies but possible sources of problems could be: - mlx5 driver in combination with vpp. Have you tried vpp’s native rdma based driver [1]? - TSO is not enabled by default for tcp in vpp. To enable it, you’d need to change

Re: [vpp-dev] VCL client connect error

Hi Satya, Why are you commenting out the group (gid) configuration? The complaint is that vcl cannot connect to vpp’s binary api, so that may be part of the problem, if the user running vcl cannot read the binary api shared memory segment. You could also try connecting using private connectio

Re: [vpp-dev] vpp_echo UDP performance

Hi Dom, UDP is without any flow/congestion control. That is, there is nothing to push back on the sender when it over drives the receiver. Increasing the number of rx descriptors probably helps a bit but unless the rx nic is faster, I don’t know if there’s anything else that could avoid the dr

Re: [vpp-dev] vpp_echo UDP performance

Hi Dom, Now that you mention it, it’s the same for my nics. Nonetheless, the packets that reach ip4-local are marked as having a valid l4 checksum. Check in ip4_local_check_l4_csum_x2 and ip4_local_check_l4_csum if ip4_local_l4_csum_validate is called or not. If not, there’s no extra overhead

Re: [vpp-dev] vpp_echo UDP performance

Hi Dom, That’s a really high vector rate. What cpu are you using? I’ve tried your config locally and I’m getting under 10Gbps with high rx drops. On the other hand, with vcl test client/server apps, after a bit of tweaking, I can saturate my 40Gbps nics with udpc (udp connection pinned to a t

Re: [vpp-dev] TLS configuration & throughput

Hi Dom, First of all, tls code is not optimized and there are some scheduling inefficiencies that we are aware of and which do affect overall performance. Having said that, you might be able to improve throughput by increasing rx and tx buffer sizes (any reason for keeping them that small?).

Re: [vpp-dev] TLS configuration & throughput

Hi Dom, Out of curiosity, I tried out testing tls throughput with iperf. Note that this is a bit of a hack, i.e., ldp can transparently convert tcp connections into tls connections if the right environment variables are set (see more [1]). Sporadically, this does exhibit some setup instability

Re: [vpp-dev] TLS configuration & throughput

Hi Dom, Is the iperf client returning an error or does it crash? Do you get any errors in /var/log/syslog? Also, do a “sh session verbose” on both nodes to see if there’s any data pending in the rx/tx fifos. Regards, Florin > On Feb 26, 2020, at 10:26 AM, dchons via Lists.Fd.Io > wrote:

Re: [vpp-dev] TLS configuration & throughput

Hi Dom, It could be that you’re hitting more often the issues that I also encountered locally. And yes, I noticed that even the server side has sporadic issues. Given that iperf works fine with tcp, I assume tls re-segments data in a way that iperf does not like. Now, with respect to the thr

Re: [vpp-dev] Multiple UDP receiver applications on same port #vpp-hoststack

Hi Raj, Now that’s interesting. VPP detects when an application dies (binary api mechanism) and forces through the session layer a de-attach which in turn leads to an unbind. In case of udp, not tcp, we have a shim layer that redirects udp packets to whomever registered for a certain port. I

Re: [vpp-dev] Query about internal apps

Hi Ole, Vivek, If I understand this right, you’re looking to intercept l2 packets in vpp (supposedly only from certain hosts), process them and maybe generate some return traffic. What is the payload of those l2 packets? You could write a feature that inspects all traffic on a certain interfac

Re: [vpp-dev] A question about using packetdrill test vpp hoststack

Hi Longfei, For protocol correctness, the only tool I’ve used is Defensics Codenomicon, which has about 1.2M tests and only needs an http terminator. Therefore, nginx + ldp is enough. Having said that, it would be great to also support packetdrill. As for your issue, I’m not entirely sure wh

Re: [vpp-dev] Is there any Linux FD to poll for VCL message

Hi Murthy, Yes it does, although we’re guilty of not having it properly documented. The message queue used between vpp and a vcl worker can do both mutex/condvar and eventfd notifications. The former is the default but you can switch to eventfds by adding to vcl.conf "use-mq-eventfd”. You can

Re: [vpp-dev] Is there any Linux FD to poll for VCL message

Hi Murthy, Glad it helps! By construction, when vcl is initialized (vppcom_app_create()) only one worker is initialized. As long as you don’t register other workers (vppcom_worker_register), you don’t really have to worry about anything else and there are no performance penalties. It’s import
