Adaptive Server versions 15.7 ESD #2 and later allow you to share query plans, which are cloned from primary query plans, avoiding the need for Adaptive Server to create or recompile query plans that are identical to existing plans.
You should see a performance improvement as Adaptive Server shares query plans instead of reusing or recompiling them. You may see a slight change to procedure cache memory usage as primary query plans are pinned in the cache while Adaptive Server uses their shared query plans.
