Description
When dragging elements in Whiteboard collaboration, the network bandwidth spikes to 50Mbps+ (observed via browser DevTools/network monitor), triggering my server's rate limits. As the dragging operation continues, the lag gets progressively worse until the dragged element completely freezes. This does not occur on excalidraw.com (2 - person test: stable at <5Mbps during dragging).

Research direction
Start by reproducing a two-person dragging session in the Whiteboard and inspect the browser DevTools network monitor while the bandwidth, lag, and freezing develop. Compare the results with excalidraw.com; done means dragging no longer causes the reported 50Mbps+ spike, progressive lag, or freeze.
