In this chapter, we successfully covered everything you need to get started with thread pools, process pools, and future objects. We looked at the various ways you could instantiate your own thread pools and process pools as well the advantages of using thread and process pool executors over the traditional methods.
You should now have a good appreciation of how we can improve the performance of our multi-threaded, multi-processed applications by utilizing this pooled-resource concept.
We also looked at how we could improve the existing implementation of our web crawler and refactor it so that it was easier to follow, and utilized some of the key concepts featured in this chapter. In the next chapter, we'll be looking at how we can utilize multiple processes within our applications, in depth.
