We are talking about *scripting* languages and *script* engines here. AISB, *there*, the most efficient implementation of an algorithm – that is, of the *same* algorithm – is *necessarily* the built-in one because if you implement that algorithm – again, the *same* algorithm – by yourself *in a scripting language*, your code has to be parsed and compiled first, and only *then* the resulting bytecode or machine code is executed by the (virtual) machine, while the built-in code is compiled already and can be executed *directly*. Also, the built-in code is in several important cases written in such a way that it makes the best use of available memory (AISB, it is logical to assume that script engine developers know what they are doing and do not intentionally leave memory leaks; assuming otherwise, i.e. that script engine performance would have a trend to get worse with time and such a script engine would *still* prevail to be available for execution, is nonsense), while that is not true of script code (one relies on garbage collection there and has _not_ full control of memory usage). We are not talking about milliseconds and kibibytes in specific script engines here, but of *overall*, *general* performance. I am sorry that you cannot see that 1 + 1 > 1 truly is self-evident and not an opinion. -- PointedEars FAQ: <http://PointedEars.de/faq> | SVN: <http://PointedEars.de/wsvn/> Twitter: @PointedEars2 | ES Matrix: <http://PointedEars.de/es-matrix> Please do not cc me. / Bitte keine Kopien per E-Mail.
