Which is better for performance? And vs AndAlso

Question

When writing an If statement, I\'ve always used And when needed like:

If 1=1 And 2=2 Then

The only time I ever used AndA

Answer 1

When the conditions are also functions:

If functionA() And functionB() Then

...

public shared functionA() As Boolean
  IF A is false THEN log -> return true or false

...

public shared functionB() As Boolean
  IF B is false THEN log -> return true or false

Using AndAlso here could be the wrong way to go, because then it will only log B when both A and B are false.
