Nginx as a reverse proxy - A closer look at Nginx worker processes and worker connections
#nginx #performance #tomcat
In this video we talk about nginx performance tuning. We look at some of the key directives related to worker processes and worker connections. We also walk through a quick demo using, nginx(acting as a reverse proxy), tomcat and jmeter. In this demo we simulate performance bottleneck with nginx as well as tomcat.
Source code shown in the demo is available here github.com/alternativedegree/nginx-tuning
Intro 00:00
Nginx Directives 02:49
Code Walkthrough & Demo : 06:05
Load Test Using Jmeter: 15:15
Identifying Performance Bottlenecks: 16:00
