Chapter 5. Optimizing I/O Performance
This chapter addresses issues that often occur when you take your functionally tested application and split it up into parts for deployment. Your web servers host the frontend code, your database is somewhere else in the data center, you may have a Storage Area Network (SAN) for centralized files, an app server for APIs, and the virtual disks are all on different machines as well.
These changes add significant latency to many common operations and your application now becomes super slow, probably because it's too chatty over the network. In this chapter, you will learn how to fix these issues by batching queries together, and performing work on the best server for the job. Even if everything runs on one machine, the skills that you'll learn here will help to improve performance by increasing efficiency.
The topics covered in this chapter include the following:
