Answers.Text: @ferit, I just tried it on CentOS Linux 7.4 with Chrome Version 63. The sliders are there and moving the slider does affect CPU usage as expected. Maybe it's not supported by Chromium, or at least the version you are using? The process that actually uses the CPU is called nacl_helper, and apparently it's a feature that can be disabled in Chrome. I recommend investigating more along those lines.

Answers.Text: Hmm I think the issue is the old Chromium. Apt installation installed a very old Chromium version I think, which doesn't have NAtive CLient. I'll let you know when I verify it.

  The menu for the analysis board has sliders for CPUs and memory (see screenshot below). Have you tried adjusting those? Maybe whether they actually work or not depends on which browser you are using. If they don't, I think this question would be best suited for the [Lichess feedback forum](https://lichess.org/forum/lichess-feedback), since it might be a bug.
