Hello, all
Glad to announce that the project VSAP(VPP Stack Acceleration Project) is
online and this project aims to establish an industry user space application
ecosystem based on VPP host stack. VSAP has done much work to optimize VPP host
stack for Nginx, and we can see some exciting
We have some test for VCL based on application too, and it looks fine. To
understand more, you’d check what line in mspace_malloc trigger the signal.
Attached is our vcl.conf for you to try if it is okay.
vcl {
rx-fifo-size 5000
tx-fifo-size 5000
app-scope-local
app-scope-global
api-socket-name
You can install any OpenSSL version as you wish, and you can use the following
command to tell vpp cmake to get the right OpenSSL
For example:
# export OPENSSL_ROOT_DIR=/usr/local/lib64/
# export LD_LIBRARY_PATH=/usr/local/lib64/

Hi, Nataraj
We have done some work for VCL performance evaluation and integration, and
currently due to VPP does not support port-reuse yet, some test tools such as
wrk which initializes client close could not give us good CPS number, thus we
are focusing on RPS. From our testing, the

Hello, all
I will use a new API added in openssl 3.0.0 master for a better async
communication, but I found that some API in openssl 3.0.0 has deprecated, such
as EC_POINT_get_affine_coordinates_GFp/EC_POINT_set_affine_coordinates_GFp.
I added a patch to fix this problem to make VPP compatible

There are two solutions.
1) DNS level: Set your own DNS server, and hijiak all DNS and point to
your server.
2) IP and http: When gateway gets request from client to google.com, and
you can simulate “man in the middle” to syn/ack to client, and talk with client
to provide 302
Thanks Damjan. If cloning a brandnew repo, the build is ok.

Even though performance is important, and we still need to use lock to resolve

Hello, all
I am now debugging an issue observed in echo server/client. If nclients ==
small number, then everything goes smoothly, but if nclients is big, such as
500, 1000, echo client will hang without printing final report, and debug shows
that echo client is waiting for response from
