Total number of records retrieved by SOQL queries - 50000

It is mentioned that total no of records retrieved by SOQL queries in an apex context should be 50000.

I have a large Visualforce page with lots of data displayed in several grids and charts.

It was running fine but now Getting error - reached 50001 rows.

Trying to fix this error. Just getting confused about apex context.

does all the queries executed on visual force controllers comes in a single apex context ? If not how the apex engine decide an apex context ?

New to salesforce development. Primarily a dot net developer.

In two or more properties of my controller I want to access values from another controller's properties.

This is how my controller is looking -

Controller1 POutlook = new Controller1();

 public Decimal currentMonthActualPer {
       get
        {
          return Controller1.currentMonthActualPer;
        }
    }
     public Decimal currentMonthForecastPer {
       get
        {
          return Controller1.currentMonthForecastPer;
        }
    }
    Public String currentMonthBackground{
       get
        {
          return Controller1.currentMonthBackground;
        }
    }
  

In my visualfocepage I am accesing this properties directly as -

{!currentMonthActualPer} and {!currentMonthForecastPer}

Now, I am not sure about Page life cycle of Apex page just wanted to confirm that Apex engine will execute statement -

Controller1 POutlook = new Controller1(); only once or will it call it every time a property's is called(Binded) in visualforce page.

Lot of calculation code has been written Controller1 constructer so just want to execute it once only.
