The number of threads to be used to accept connections. Increase this value on a multi CPU machine, although you would never really need more than 2. Also, with a lot of non keep alive connections, you might want to increase this value as well. Default value is 1.

- Looking at the [Tomcat connector docs](https://tomcat.apache.org/tomcat-7.0-doc/config/http.html) I think we really need to increase `maxThreads`
- The default is 200, which can easily be taken up by bots considering that Google and Bing each browse with fifty (50) connections each sometimes!
- Before I increase this I want to see if I can measure and graph this, and then benchmark
- I still want to bump up `acceptorThreadCount` from 1 to 2 as well, as the documentation says this should be increased on multi-core systems
