For example - See these 2 macros When we save the macro, it is virtually compiled and unlike it's human readable form as we saw in VBE(Visual Basic Editor), keywords(the dark blue words which you cannot use as variable) are saved as three-byte token which are faster to process as machine understand them better and variables, comments and literal strings which are not either keyword or directive are saved "as is".

However VBA compiler tokenizes the word but it does not compress the lines and each line is maintained as is ending with the 'Carriage Return'.

If any other references point to the same object, the object will not be destroyed.

Reduce the number of Lines: Avoid multiple statements especially when they can be clubbed into one line.

When we combine multiple lines using colon into one line, we're reducing the number of fetch cycles the processor must go through.

Our Suggestion: This change will bring minor difference in time due to faster processors today.

You must set the Screen Updating property to True when the procedure finishes or when it stops after an error. Turn off automatic calculations: Whenever content(s) of a cell or range of cells are changed, the formulas dependent on them and Volatile functions are recalculated.

You can increase the speed of some procedures by keeping screen updating turned off.

"VB does not let you manipulate pointers" is more precise. If all we ever use are object pointers, how can we set the object itself to Nothing? When we set a reference to Nothing, something called the garbage collector kicks in.

We rarely fire an event for each cell we're changing via code.

Enable Events to tell VBA processor whether to fire events or not.

When the VBA macro is executed, VBA processor fetched single line at a time.

The tokens of the fetched line saved by virtual compiler are now interpreted and executed then next line is fetched and so on.

Behind the scenes, VB still makes extensive use of pointers. This little piece of software tries to determine whether or not an object should be destroyed.
