29 CHAPTER 1 „ OHS, EPG, AND APEX LISTENER COMPARED Table 1-1. 55 ~ 11 times faster You can see from the benchmarks that when mod_gzip is enabled, the web server is able to handle roughly eleven times as many active connections; in other words, an order of magnitude more connections. That is a huge benefit from a relatively simple server configuration change. You can also see that the bandwidth savings are significant too (in terms of the difference). It is easy to overlook the benefit that a reduction in bandwidth would have; after all, network speeds are getting faster and faster all the time, so who really cares?

I also covered some of these techniques in my first book, Pro Oracle Application Express. ”. Well, these techniques can have such an impact on the performance and scalability of your applications that I won’t stop talking about them until I’ve convinced every last one of you that they’re worth investigating!

These are overarching concepts and I won’t rigidly stick to them, but they give you a general idea of the sort of things I believe are important. Rather than jumping back and forth between the different options (which could be confusing), I’m breaking the rest of the chapter into three parts to cover each of the options and show the various possibilities and features provided by each of them.
