disable engine output in game play

[quantum]

I am quite new to programming, especially chess programming. Though I will ask some questions here from time to time.

I wonder if there is any significant speed gain in game-playing mode when you disable the permanent engine output and only write a line at the end of search?

There's a slight overhead (more pronounced in hyper-speed chess), but negligible overall.

It's probably less than 0.001 elo.

I think it will depend on the engine. Mine is 35 elo worse with noise output in ultrafast games. (I hide for the first 250.000 nodes). Probably it should be innapreciable for longer time controls.
