# Informatica – Session Performance

Optimizing **informatica** is a challenging task. Sr Developers work on it. There are various methods we can improve performance:

Related[Informatica – Source Optimization](https://srinimf.com/2013/12/19/informatica-source-optimization/)

1) We need to use Grid [to increase](https://srinimf.com/2015/08/30/mainframe-how-sortwkxx-datasets-increases-sort-performance-in-jcl/) session and wf performance

2) Use push down optimization. IS will run SQL query either in Source/Target

3) Run session/wf concurrently

4) Increase DTM buffer size, Optimize buffer block size

5) Increase cache size etc..
