 NOTE: we're mostly bottlenecked by the architecture (typically a Lua VM) and the intentional bottlenecking from call costs.
 
 - make signals use a circular buffer instead of a simple array
-- use a hashmap for components (and device info), this may require reworking how iterating over them is handled
+- use more arenas if possible
