If you are facing performance issues in axapta then you can take following action.
1. Re-Indexing.
2. Create new indexes by getting hints from long query and select queries.
3. Check unwanted data in log tables and clear them if not required.
4. Increase RAM Size in sql database.
5. Check your disc where application and database installed. Required to check whether its free or not.
6. Check blocking processes from sql at working time.
7. Load balancing of AOS.
I hope you get good hints from here for performance tuning.
