A few points about the slow startup.
When you explicitly specify which fields you really need the system will
completely 'not load' the rules that have no impact. Especially if you do not
need the DeviceBrand/DeviceName the impact will be quite large. You can simply
pass something like this .withField("AgentName") .withField("DeviceClass")
.withField("AgentVersion") and it will have a big impact on both startup times
and run times for a not yet cached parse.
I had a look at your project and with this patch the startup time drops to
less than 1.5 seconds.
