Application Performance Issue

Hello,

We need to perform few steps to optimize your code and application performance,

1. Collect Information
   • collect all information about application module or page which is taking more time
2. Reproduce the Issue:
   • Try to reproduce issue where it is taking time.
3. Use Profiling Tools
   • use profiling tools to identify rootcause for slowness
4. Analyze Profiler Results
   • Analyze profiler results which will help to find actual rootcause
5. Identify Root Cause
   • based on above steps we need to identify rootcause of slowness then need to take appropriate step to solve it.  ??????
6. Optimize Code and Queries
   • try to optimize code and queries whic are taking more time in page.
7. Implement Caching
   • If possible we can implement caching which will help us to improve response time while response from cache rather then database query.
8. Database Optimization
   • need to check on database side as well if possible we can check on table index, store producedure, functions etc. 
9. Parallelism and Asynchronous Processing
   • if possible we can implement parallelism and asynchronous call to display results in page without blocking user page.

    10. Filter Data Early

• If possbile we can implement filter server side Using WHERE clauses to filter rows as early as possible in the query execution process.

11. Optimize Joins

• Avoid unnecessary joins and limit the number of joined tables.

• Consider using EXISTS, IN, or JOIN instead of subqueries for improved performance.
