I believe you're wrong.

Symbols are resolved into references to the symbol table at parse time, 
so when running, :s and :ssssssssssssssss are just two different 
pointers into the same symbol table. As for local variables, they are 
just offsets into the stack frame.

So it might take a microscopically small amount of extra time for your 
program to start up, reading a few extra bytes of source code, but once 
it's running, each iteration should take the same time.
