Hi all. Here is an excerpt from a chicken-profile for one of my programs:
procedure calls seconds average percent ------------------------------------------------------------------------------- ... symbol-compare 1058128414 3467.563 0.277 13.7471 ... I was surprised by the high percentage for symbol-compare which I don't see with other Schemes: (define symbol-compare (lambda (a b) (string-compare (symbol->string a) (symbol->string b)))) (define string-compare string-compare3) ; for example I looked at the definition of symbol->string and found out that it is not a constant operation (like returning some pointer) but constructs a string. Does anyone have a more efficient comparison of symbols implemented? BTW: the average above is wrong (because of format-real in chicken-profile.scm). Greetings Sven
