Description

While investigating the reasons for the java client occasionally not being able to negotiate the connection within a reasonable time, we noticed that there is often a time gap between receiving connection-start and the client responding with connection-start-ok.

Upon further investigation it appears that getPid() and getPlatformInfo() is a contributory factor.

These values are per JVM and there is no reason to fetch them for every connection. Instead we should fetch them in a static block and then return the cached value when the getters are called.
