Thread delay in run loop

Synchronized
Synchronized methods are slow, since an object lock has to be obtained. Avoid them if you can.
Method parameters
The number of parameters passed into a method affects performance. If you can't remove a method, try to have a minimum number of parameters passed into it.
Bitshift operators
Bitshift operators are faster than multiplication and division operators.
Instead of:
x / 4
use
x >> 2
Instead of:
x * 4
use
x << 2
--> As if the compiler doesn't know this...
Loops
Leave as much code as possible outside loops.
