Static Variables are slower than Dynamic ones

Referencing a static local variable in a procedure is 2-3 times slower than a regular local, dynamic variable; if you want to really speed up your procedures, convert all static variables into module-level variables.

The only drawback to this approach is that the procedure become less self-contained and if you wish to reuse it in another project you must also remember to copy and paste the module-level variable. An alternative approach is loading the value of a Static variable into a regular, dynamic variable before using the variable in a time critical loop.
