Hi there. What exactly is the scope regarding your performance issue? pl/sql code? or sql statements only?, I can be of help in any fo those. But I will need access to your database, I have my own oracle databases to recreate your environment but such practices are not always very helpful regarding performance issue. What database version? what operating system?

Experienced software solution architect with over 25 years in the design and development of large applications. Have a good knowledge of Oracle/SQL Server/MySQL/PostgreSQL and other databases. Have done a lot performance tuning of large applications (both front-end as well as back-end) Some of the work that was done in the past for the clients 1. Improved the performance of screen loading to less than 3 seconds. Earlier it was taking more than 15-20 minutes. This was a client server application written in dotnet with SQL Server as back-end database 2. Improved performance of a PowerBuilder application where it was taking more than 7 minutes to lead a few screens. Optimized the oracle queries and got it down to less than 10 seconds 3. Optimized the dynamic queries of a ASP .net application and got down the report generation time to less than 3 seconds for 70% of the queries and the rest to less than 10 seconds. Initially these queries were taking more than 5 minutes and in some cases were timing out. All these queries were complex queries operating on millions of records 4. Optimized the queries for a large financial application reducing the response to less than a second from 3 seconds which increased the application performance
