CPU Usage - Scriptnode

[lalalandsynth]

We are working on a plugin that I would expect to be quite low on CPU , no audio , only CC output.
Its completely done in scriptnode and its showing me 0.12-0.14% cpu in the performance meter in Reaper.

Native Reaper convolution reverb is 0.3%.
Serum with a complicated patch is 0.14-0.15%

So a simple plugin only outputting sitting at 0.12% seems quite high.

How would you go about tracking down what causes the high cpu usage?
Is it advisable to compile my whole scriptnode setup into a dll ? Would that reduce CPU use ?
