I have a Laptop as you see in pic with ssd. But i have never reached such fast generated strats as you in your video? Is that manipulated? Or do you have make faster in video?

Can you do me a quick favor and look at this one?

Should be an easy fix. Thanks so much.

Other reason may be that the Generator finds different strategies, pushes to Collection and draw chart. This all may take different time.

I wrote a simple speed test that calculates one strategy 1000 times and shows the time in milliseconds.

In order to do the test follow the steps:

1. Open the core app here: https://eas.forexsb.com/

2. load MetaTrader Demo Data H1 in Editor.

3. Open the Developer Console (F12)

4. Paste the following function:

function speedTest(cycles) {
    console.log("Test started. Please wait...");
    const strategy = eas.strategy;
    const settings = eas.settings;
    const dataSet = eas.dataManager.dataHolder["MetaTrader-Demo EURUSD H1"];

    const startTime = Date.now();

    for(let i = 0; i < cycles; i++) {
        strategy.setAllIndicatorsDirty();
        BacktesterHelper.calculateStrategy(strategy, dataSet);
        Backtester.calculate(strategy, dataSet, settings);
    }

    const time = Date.now() - startTime;
    console.log(cycles + " cycles calculated for: " + time + "ms");
}

5. Run the test with this call: speedTest(1000);

It shows 10250 - 10750 ms on my machine on Chrome. Lower is better.

Edit: The result greatly depends on what strategy you have in the Editor. You may test with more complex or more simple.

Vini benchmark

Chromium (compiled with Polly optimizations) v67.0.3380  vs Firefox Quantum 59.0.2

I've record the session with one computer(my notebook) and use other (my pc) to do the experiment just to avoid consume cpu with the main computer while recording.

Benchmark Data and Time

Results

For my environment (i5-3.8ghz 7 gen, ssd, windows 10) Firefox Quantum 59.0.2 was faster than Chromium v67.0.3380 by a little. Maybe with long time runs +12 hours the difference can be better.

I will recommend to everyone if you use chrome that you can create a new chrome user and use it without chrome extensions just for generation purpose. Some chrome extensions consume cpu.

I've done my part, thank you @geektrader for the contribution and for sharing yours discoveries.

See you guys

Thanks again for this test, I have tested exactly the same Firefox Quantum 59.0.2 vs Chromium 67.0.3380 now and can confirm you results! It´s very odd, either Firefox Quantum has got a huge speed-boost from the version 59.0.0 I had tested in my original video, or Chromium 67.0.3378 -> 67.0.3380 got a lot slower. I will do more tests and report back. Quantum 59.0.2 even beats out Microsoft Edge now! Crazy stuff and interesting how the speed can change between minor browser versions! So this is something that must be re-tested over and over again as it seems.

Cool, so you see the same in that relation, great!

sorry edge was faster for 10minutes after that chrome was faster

On the other hand here is one more interesting find: Microsoft Edge (from latest Windows 10 Insider preview) does beat Chromium slightly here on my machine, didn´t expect that!!

Anyhow, just use what is the fastest for YOU. The whole point of this post was to make people aware that there can be huge differences between browsers with EA Studio, so test, then use what´s the fastest for you to not waste CPU cycles :-)

Good luck!
