I believe the reason the performance is trash may have to due with how the frequency scale has been changed. To fix the emulator to work at different sample rates, changes were made to the timetable generation code. Changing the onSampleRateChange
function to mimic the old behavior seems to bring the performance back down, but obviously breaks the module's ability to produce the correct signals.
Another reason the performance explodes in polyphonic mode is that this implementation uses 16x emulations vs the CV2612 that only allows 6-channel polyphonic input using the 6 voices on the chip.

Resolved as of 1.8.0. YM2612 emulator was rewritten to remove a ton of bloat related to the old emulation context (Sega MasterSystem/MegaDrive emulators). The 6 voices were replaced with a single voice in favor of VCV polyphony since the 6 voices were just naively summed and clipped using finite point maths (6 voice functionality achievable by placing 6 modules on the rack).
