Question

I am using rails 2.3 with Oracle database. Application is already running but database is having 2GB+ records now. I am told to perform optimization in the database.because now page is loading quite slow.and we found queries are taking much time.
and daily atleast 1000+ records are inserted into database

Would anybuddy let us know where should I start from?

Answer 1

• Find the real bottlenecks. Which queries are the slow ones?
• If you found the slow queries, check the indices and add new ones where necessary.
• If you do a lot of single queries check, if you can combine them in joins and return larger chunks of data in one query.
