 * the # of ingest clients (xqa-ingest-balancer's pool_size).
 * how long each ingest client waits for a xqa-shard size response  (xqa-ingest-balancer's insert_thread_wait & insert_thread_secondary_wait)
 
-In general the "best" overall scalability & performance is achieved when the # of BaseX engines and ingest client's is less than the maximum # of host CPU cores.
+This ability to experiment is important as it let's you tune XQA to match your requirements.

+In general though, the "best" overall scalability & performance is achieved when the # of BaseX engines and ingest client's is less than the maximum # of host CPU cores. 
+
+By reviewing the graphs below, from a worst case ingest using a single BaseX engine, we can achieve somewhere between a 250% to 400% improvement in performance by using XQA.
 
 ### 1.1. Test Data
 * Each test run used all the .xml files from [xqa-test-data](https://github.com/jameshnsears/xqa-test-data).
