From a common log (times are in microseconds)

Render time: 1940
Copy time: 7124
Encode time: 152556
Send time: 1447
Draw time: 163226

The copy time is excessive for being just a copy and the encode time is very big.

This shows that excluding the copy and the encoding, it might be possible to send the data in real time from the backend to the frontend to implement the interactive plot. Time is around 1~10 msec. 60 fps asks for a frame every ~16 msec, for comparison.

Use xtl base64 instead of cppcodec. Even faster rendering.

As a bonus there is one less dependency.
