A simple stress test of apisix and nginx

[Lewisyixin]

I did a simple stress test of apisix&nginx, and found performance of apisix is little better than nginx, is it normal?
In my opinion, performance of apisix should be a little worse than nginx.

nginx and apisix are on the same vm and proxy_pass to the same upstream
nginx:
version: 1.20.1
config:

result:

apisix
version: 2.14.1

result:

During the performance test, are the CPUs of nginx and Apache APISIX fully loaded?

Also make sure the machines for running APISIX and Nginx are same and the number of worker processes should be same.

I use "worker_processes auto;" on the last performance test(both nginx and apisix and they are on the same machine).
I did a test again today. First I change there "worker_processes auto;" to "worker_processes 1;", and got samilar result.
Then I increased concurrency to make sure cpu would be fully loaed as much as possible.
The result is that performance of apisix is still a little worse than nginx but load of nginx is lower than apisix.
Is this as expected？

nginx

apisix

Looks like you don't enable keep-alive for Nginx. Add following two directives in your Nginx conf.

proxy_http_version 1.1;
proxy_set_header Connection "";

Oh, that's right! Performance of nginx is a bit higher than apisix after enable keep-alive.
