Thread: Why doesn't Jagex use Bitwise OR for their buffers?

All that argument is about your statement: "OR is faster than addition" while performance is completely platform-dependent.

iKilem obviously stated that he would use OR over addition so why would you suggest him to use addition? Stop fighting.

so every platform has better addition performance, wouldn't you think that using OR no matter what would be more beneficial to the ones who don't have fast addition? What I read (and iKilem) is that OR is always faster it is just a matter of how much faster, with newer processors it is about the same.

I said that OR was faster.

NOW if you actually have some documents or evidence to stand against that statement, then click the back button on your browser. Leik now would be a good time

"wouldn't you think that using OR no matter what would be more beneficial"
^ this
OR > addition, but OR is not always faster, which makes your statement "it's faster" invalid.
Don't wanna discuss this anymore since I'm not "your level". I might be wrong.

lol and where did you get the information saying that it's not always faster? wikipedia says it is ALMOST as fast on some newer processors

and i could care less where you rank me on your "programmer scale" because i don't need to hold myself above you when i don't even know you

According to this document: http://gmplib.org/~tege/x86-timing.pdf, most x86 processors take the same number of clock cycles to for the ADD and OR instructions.

thank you, someone actually gives some reputable evidence rather than hearsay and personal opinion..

Ikillem kept giving the argument: I can't say anything about performance because I don't have evidence so I won't. <--- no opinion attached, just leaves the options open, valid argument.

then you said: OR has better performance without giving an example why it would be... <-- chooses an actual side, without underpinning the argument => opinion


now who is using invalid arguments son... pisses me off when people rage about things they are doing themselves

I don't remember reading that OR is always faster. I said it was platform- you know what I said.

Hearsay? Point me to one of my comments where there is hearsay.
