Resource recommendations for Adaptive Server 15.0

Adaptive Server 15.0 requires more procedure cache than version 12.5. This increased memory requirement applies to optimization as well as to query execution. Sybase recommends that you increase your procedure cache 2 – 6 times the size of your procedure cache in Adaptive Server 12.5.

You may also need to increase the space on tempdb for query processing on Adaptive Server 15.0.
