Slow response time
Closed this issue · 4 comments
Describe the bug
I have done some comparaison between running nginx + fpm vs swoole with FostHtppCacheBundle.
on locale with fpm, I have response time never go over 18ms to serve a simple cached json result which is stored in a file on the disk.
On the other hand. for the same call on swoole it take 28ms minimum up to 40ms.
So fpm seem lot twice faster.
Do you know any tweek I can do to improve swoole response time?
Environment (please complete the following information):
- OS: Mac
- PHP Version: 7.3.13
- Symfony Version: 4.4
- Running in docker: No
- opcache: enabled
Could you please provide us more information, especially a swoole bundle configuration?
Also please try bellow configuration options:
swoole:
http_server:
running_mode: reactor
hmr: off
settings:
reactor_count: auto
worker_count: autowith symfony production settings (APP_ENV=prod, APP_DEBUG=0)
On my laptop:
cpu: Intel(R) Core(TM) i7-5500U CPU @ 2.40GHz
ram: 8 GiB
linux kernel: 5.4.15-arch1-1
php: 7.4.2
swoole version: 4.4.12
Project: https://github.com/k911/swoole-bundle-symfony-demo/
Produces the following results:
APP_ENV=prod APP_DEBUG=0 ./bin/console swoole:server:run
