How do you improve web application? what are the tools you have used? (Or how do you check performance)

Question

Accepted Answer

To improve web application, I use tools like profiling, caching, compression, and optimization.

I use profiling tools like MiniProfiler and Glimpse to identify performance bottlenecks.
I implement caching using tools like Redis and Memcached to reduce database queries and improve response time.
I use compression techniques like Gzip and Brotli to reduce the size of files sent over the network.
I optimize images, scripts, and stylesheets to reduce page load time.
I monitor application performance using tools like New Relic and AppDynamics.
I conduct load testing using tools like Apache JMeter and LoadRunner to identify performance issues under heavy load.
