Any ETA on this? We're using whiteboard, not overly complex (between 100-200 items), which should serialize pretty quickly. Now the whiteboard freeze for about 5 seconds after each simple change we make. This is pushing us to other tools.

Hey Jakub, thanks for the feedback. Lag is on our radar and we have a few fixes just about to land. To help investigate: roughly how many objects on the board, what actions trigger the lag (zoom, pan, dragging items), and which browser and OS. A screen recording or link to the board would be even better.
