c# - ASP.NET Website Slow Performance on production server

Question

My problem is that my ASP.NET website is running slower on my production server comparatively on my development server.

A page that executes in 120ms in my development environment takes 400ms to execute on the server. I've monitored the SQL server with the profiler and the query being run on the page taking 400ms on the server only takes around 50ms to finish - so I've convinced myself that my problem does not lie with the SQL server.

My development machine is an Intel I7 with 6GB RAM, the production server is a 2x AMD Quad Core with 16GB ram.

Answer 1

There are some point you can consider for performance improvment of your website.

1. Set debug=false
2. Turn off Tracing unless until required
3. Turn off Session State, if not required. ASP.NET Manages session state automatically. However, in case you dont require Sessions, disabling it will help in improving the performance
4. Disable ViewState as and when not required.
5. Avoid Frequent round trips to the Database
6. Avoid Throwing Exceptions. Exceptions are a greate way to handle errors that occur in your application logic. However, throwing exceptions is a costly resource and must be avoided. Use specific exceptions and use as minimal as possible to avoid resource overhead
7. Use Caching to improve the performance of your application.
8. Use Finally Method to kill resources
