The Generator uses a specialised version of the Genetic algorithm.
It first generates a random entry indicator with random parameters. Then it modifies teh strategy by gradually changing all the variables that determine the strategy: parameters, indicators, SL, TP...

It happens sometimes the Generator to find a stable strategy that affords many modifications. In such a case, the Generator can push many relatively similar strategies to the Collection. This doesn't mean that the Generator is faster. it only means that it has found a good combination of indicators for the particular market and with gradual modifications, it is able to produce many strategies.

In order to confirm your observations, you have to run the Generator with the same settings multiple times on the testing machines. The best thing to do it is to reset the settings and to limit the Data to a particular number of bars.

Then:
- empty the collection
- run the Generator for 1 minute.
- note the count of generated strategies and the count of the collected strategies.

Repeat the above test 30 times on your faster and on your slower machine. Please use the same data for all of your tests.

For example, I run the test on my development machine on 100 000 bars M1 EURUSD and got:

Test,   Generated,  collected
1          1387            9
2          1465            9
3          1432            5

Do that and we will discuss the results.
