I agree, I have benchmarks planned for the future.
As far as the latency on MeowDisplay, In my testing on Wifi, I measured around 14-17ms median from capture to receiver handoff, not e2e. I've also seen occasional spikes around 50-90ms and some stalled frames, you do notice the stalls but overall it's pretty responsive.
I've preferred to show the cursor as it is on the mac instead of rendering it locally on the phone which may make it feel smoother but the trade-off is that it may not accurately represent where the cursor actually is on the mac if things lag or hang.
Then again, it does depend on the connection.
