optimization speed

 
Hello friends, 
I have a question about mt5 strategy tester.
When I test my expert in visual mode, it takes about 2 minutes for testing eurusd in last 6 mounts, but when I want to use optimization, it take 3 hoarse to test only 10 cases. 
I select "fast generic based algorithm" but it is very slow...
Can anyone help me in this Problem?
 
It's not testing “10 cases.” It is testing thousands; only 10 are profitable. Right click → Show useless results and rerun.
