[vpp-dev] Issue in building vpp
Hi Team,
We are trying to build VPP on ubuntu 20.04 with kernel version:5.4.x.
We cloned the gerrit code: https://gerrit.fd.io/r/vpp
When we try to build with : /build-root/vagrant/build.sh, we see below issues:

We have seen posts on similar issue (vpp-dev@lists.fd.io | Arm build failures
on Qualcomm, ThunderX2, Mellanox
Bluefield),but
couldn’t find a proper answer.
We tried with a stable version also, but seeing same issue.
Can anyone please share your points on this.

[vpp-dev] [fdio2106]drops at memif
Hello Expert, our user application (User_App) communicates to VPP via memif. user application is configured in Slave mode. User_App sends 100msg/sec to VPP and VPP is coded to respond back to each packet. we see some weird drops at memif at ring boundary. when rx packet count on memif interface reaches around 2048, VPP drops one packet at ip-plugin. *fdio version:2106* *memif configuration in VPP:* vpp# show memif memif0/2 sockets id listenerfilename 0 yes (4) /run/vpp/memif.sock interface memif0/2 remote-name "User_App" remote-interface "memif_conn" socket-id 0 id 2 mode ip flags admin-up connected listener-fd 54 conn-fd 53 num-s2m-rings 1 num-m2s-rings 1 buffer-size 0 num-regions 2 region 0 size 65792 fd 60 region 1 size 268431360 fd 65 master-to-slave ring 0: region 0 offset 32896 ring-size 2048 int-fd 73 head 5152 tail 3104 flags 0x interrupts 146 slave-to-master ring 0: region 0 offset 0 ring-size 2048 int-fd 69 head 3105 tail 3105 flags 0x0001 interrupts 0 vpp# *Memif stats:* vpp# show int memif0/2 Name IdxState MTU (L3/IP4/IP6/MPLS) Counter Count memif0/2 5 up 0/65535/0/0 rx packets 3100 rx bytes 202802000 tx packets 3099 tx bytes 202736580 *drops 2* ip4 3100 *VPP Node Counters:* vpp# show node counters Count Node Reason 1 ip4-input ip4 ttl <= 1 1 ip4-icmp-error hop limit exceeded response sent 1 null-node blackholed packets dropped packet content in gdb indicates that packets content is overwritten partially with the content of next packet. for example, IP header for below packet is at 0x101182c98*e* which is not correct. had this been 0x101182c98*f* then this packet would have considered fine and not dropped.

Re: [vpp-dev] test performance of nginx using vpp host stack#vpp-hoststack
You can try to set the long downstream and upstream connections in nginx
configruation like this:
http {
...
keepalive_timeout 65;
keepalive_requests 100;
upstream backend{
...
keepalive 3;
}
}

Hanlin

Hi,
I test the performance of upstream server.
Just as you see, the performance of upstream is more higher than vpp proxy. In
addition, I don't find any drops.
Thanks.

Re: [vpp-dev] test performance of nginx using vpp host stack#vpp-hoststack
Next step then. What’s segment-size and add-segment-size in vcl.conf? Could you set them to something large like 40? Also event-queue-size 100, just to make sure mq and fifo segments are not a limiting factor. In vpp under session stanza, set event-queue-length 20. Try also to run the test twice to make sure the issue is not pool warmup. Finally, if perf doesn’t improve, before test do "clear error" and after test "show error” and let’s see if there’s something there.

Re: [vpp-dev] test performance of nginx using vpp host stack#vpp-hoststack
As mentioned previously, is the upstream server handling the load? Do you see drops between vpp and the upstream server?

Re: [vpp-dev] test performance of nginx using vpp host stack#vpp-hoststack
What’s the result prior to multiple addresses? Also, can you give it the whole /24? No need to configure the ips, just tcp src-address 192.168.6.6-192.168.6.250 Forgot to ask before but is the server that’s being proxied for handling the load? It will also need to accept a lot of connections. Regards, Florin > On May 4, 2022, at 8:35 AM, weizhen9...@163.com wrote: > > According to your suggestion, I test with multiple source ips.

Re: [vpp-dev] test performance of nginx using vpp host stack#vpp-hoststack
According to your suggestion, I test with multiple source ips. But the performance is still low. The ip is as follows. vpp#tcp src-address 192.168.6.6-192.168.6.9 Thanks. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [vpp-dev] test performance of nginx using vpp host stack#vpp-hoststack
Hi, That shouldn’t be the issue. Half-opens are on main because connection establishment needs locks before it sends out a syn packet. Handshakes are not completed on main but on workers. VPP with one worker + main should be able to handle 100k+ CPS with warmed up pools. Long term we’ll switch from main to first worker for syns but again, that’s not the thing that limits performance in your case. Instead, it’s probably the number of ports. You should be able to confirm that by testing with multiple source ips. Regards, Florin > On May 4, 2022, at 8:00 AM, weizhen9...@163.com wrote: > > Hi, >Is this the reason for the low performance?

Re: [vpp-dev] test performance of nginx using vpp host stack#vpp-hoststack
Hi, Is this the reason for the low performance? In general, the main threads handles management functions(debug CLI, API, stats collection) and one or more worker threads handle packet processing from input to output of the packet. Why does the main core handle the session? Does the condition influence the performance? If yes, what should I do? Thanks. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [vpp-dev] test performance of nginx using vpp host stack#vpp-hoststack
Hi, Those are half-open connects. So yes, they’re expected if nginx opens a new connection for each request.
