Some performance numbers from a simple test

[Thomas Sødring]

Hi Petter,

I took a quick look and I see there is a thread called "File Watcher"
that is simply eating up memory and using CPU resources. It's part of
dev-tools that is meant to do some autoloading.

Removing this dependency from core-webapp pom.xml

 <dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-devtools</artifactId>
 </dependency>

stops this part from eating memory. When I reran there is a thread

RMI TCP Connection(1)-127.0.01, that is also consuming resources, albeit
at a slower rate! I will try and see what this is over the weekend!
