panel info does make strategy tester slow ?

 
hi friends, I have been testing my EA that's doesn't have a panel info the test goes faster but when its have panel info its so slow can take the hole day but now I decide to have two copies one with panel info and one without a panel info for faster test I realize that without a panel info the strategy tester does goes faster thanks.

so whats the question?

 
hi why panel info making strategy tester so slow ? I have realize that with panel info the strategy tester is slower than I thought it does good when testing for 3 months history data but when testing for 4 years can take the hole day for the test to be finish.

Just a guess, but i imagine it has something to do with the constant need to draw on the chart.

 
It's quiet obvious, handling graphics requires resources, even if they are well coded. 

Making 2 different versions is probably the worst thing you can do to mitigate the problem.

Option 1: put a true/false input variable for disabling all graphics 
Option 2: put a condition to not print graphics if EA is running into the tester but NOT in visual mode.

Both of them are surely better than handling multiple versions for a so little difference among them.
