Interestingly, I'm getting a significantly higher hash rate in Chrome than in Firefox (12,000 vs. 600). This is despite the fact that Firefox has a higher priority on my OS (High vs. Normal) and they're both using the same amount of CPU.

What hash rates are you seeing on your machine/browser?

Firefox is probably slower because it uses the javascript implementation of the hashing algorithm:

Chrome implements the WebCrypto API https://developer.mozilla.org/en-US/docs/Web/API/Web_Crypto_...

I think it uses this interface: https://cs.chromium.org/chromium/src/third_party/WebKit/Sour...

I was getting ~4KH/sec then I've done some tuning and got to 20KH/sec with Chrome. I plugged in the power cord, changed from Balanced performance to High performance option. Also enabled GPU for use with Chrome instead of integrated graphics.

"At your current hashrate you can expect to mine 50 Nimiqs every 2.3 hours"

I think it's a WebRTC problem. Chrome has no errors, but Firefox has:

> ICE failed, add a TURN server and see about:webrtc for more details

This is related to your local network. You will only be able to use Websockets for connections (which most nodes do not support) and not WebRTC. Go and fix your network, you likely have some UDP or NAT configuration issue (or a terrible ISP).

Yet WebRTC works for Chrome for the same device on the same network connection?

Worse here, with chromium I can get 20kH/s vs 200H/s on Firefox.

Oh dear, 216 hash/sec on OSX Safari on a year old Macbook Pro.

Safari Technology Preview (r31) on MBP gets me 8kH/s

(Chrome on the same machine gets 12kH/s)

Huh. I fired up a Chrome instance alongside and got 8kH/s; Safari still chugging away at 2-300H/s.

11.24 kH/s - dell n5110 / chrome / win7

Linux chrome on a 4 year old thinkpad 10 kh/s

Chrome on the latest MBP, 13 kH/s

yes Firefox is way slower in general. On a Macbook with Chrome I get about 12 kH/s

5-6k i3/win10/opera

OSX Chrome 10kH/s

5.07 kH/s
