Too long compilation

Hello.
In our project we use java code generators which produce classes with hundreds of fields.
Consider synthetic example:

public class Test3 {
    private final Random fld0 = new Random();
    private final Random fld1 = new Random();
    private final Random fld2 = new Random();

    public int count(){
        int result = 0;
        result += fld0.nextInt();
        result += fld1.nextInt();
        result += fld2.nextInt();
        return result;
    }
}

I measured compilation time depends on fields count:

100.00 | 1.20
200.00 | 2.60
300.00 | 4.70
400.00 | 8.50
500.00 | 13.30
600.00 | 15.60
700.00 | 22.70
800.00 | 28.60
900.00 | 37.60
1000.00 | 44.60

for 2000 field compilation time was 200 sec with peak memory consumption 8 GB!!!
without CF compilation time was 3 sec.

We need to enable CF for hand-written code.
We generate code in annotation processors. So hand-written and auto-generated code are in the very same module.
If it is not possible to speedup compilation may be it would be a good idea to have possibility to disable CF for some classes in module?
For ex, @SuppressWarning("nullness") on a class should prevent CF to analyze methods' bodies.
