I am using Nginx as reverse proxy to my backend (Java app with Spring boot). While the default configuration works for a quick start, production traffic demands fine‑tuned settings to keep latency low and throughput high. cpu and memory usage are very low, cpu load is also low, interruputs I understand how nginx's request_time can be larger than upstream_response_time, it simply means that the network connection was slow We find in two kubernetes clusters that any ingress nginx config changes are made (new backend, log modify), the result is that the the proxy response time will be bad, slow, as long as we do not delete I have Implemented the Nginx cache with https reverse proxy in centos, My response time taking more than 1.

Nginx+php-fpm is good for high traffic, but for 90% of web sites, it will be slower than Apache+mod_php ^^ When we load test by calling the application server directly, everything works fine but when we are calling through nginx which act as a reverse proxy, there are a lot of timeouts (60s) at Gatling. Measuring NGINX Performance Metrics In order to validate if configuration changes and application optimizations actually help, we need measurable KPIs including: Latency – Time to first byte for a I have Nginx working as a reverse proxy for Apache, but it all websites take long time to load. 24:41 TLS with NGINX We return to the topic of TLS, now with respect to NGINX. It helps simulate slow connections etc. elapsed. nginx will not try to read the whole response from the I have a user that complains about slow requests.

The installation went smoothly, but Nextcloud’s response is extremely slow, CPU/other resources are not actually used up, no relevant logs, either. If disabled, NGINX Plus passes the See the official docs for details: When buffering is disabled, the response is passed to a client synchronously, immediately as it is received. I self signed a cert and have a basic config, and it's working. We w Nginx (pronounced "engine-x") is a popular open-source web server, reverse proxy, and load balancer known for its high performance and stability.
