I don't know that positing? Do you have a link?

As for CachingFeatureSource - you should be able to get better performance by 
using SpatialIndexFeatureCollection (as outlined here 
http://docs.geotools.org/latest/userguide/library/main/collection.html#performance-options).

It forces things into memory at the start; backed by a spatial index. 
CachingFeatureSource goes about it in a lazy fashion etc...

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security 
threats, fraudulent activity, and more. Splunk takes this data and makes 
sense of it. IT sense. And common sense.
