Some optimization hints...

[Z!re]

Using x+x is faster then using x*2


Using x*x is faster then using x^2
x*x is faster then x^2
x*x*x is faster then using x^3
x*x*x*x is faster then using x^4
[...]
* is faster then ^ up until (roughly):
x^15


x*n is faster then x/n
Example:
x*0.2 is faster then x/5


IF [...] THEN is faster then SELECT CASE


CONST five=5
a=five

is faster then:
a=5
(especially large numbers)


Integers are the fastest numerical type.

redim array(23456)

is faster than


for t& = 0 to 23456
array(t&)
next

using '$static makes the program run faster than '$dynamic, but i don't use '$static much anymore...

adding defint a-z speeds up the program by a bunch


use:

poke x + y * 320&, color

rather than

pset (x,y), color

poke is faster, but only use this on screen 13h.

Barok, you forgot the DEFSEG &H800 or what ever the hexcode is for it...

[Zack]

Code:

DEF SEG=&HA000
POKE X + Y * 320&, PixelColor
DEF SEG

for t& = 0 to 23456
array(t&)

I don't even get what your trying to do with that loop.

The problem with static programs is they can't have >64K arrays. This isn't always a problem and if you need large arrays, QB isn't the best method for handling them anyway.

Really? Maybe if you don't explicitly declare variables and what type they are, but only bad coders do this. You're not a bad coder, are you? ;P

use:

poke x + y * 320&, color

rather than

pset (x,y), color

poke is faster, but only use this on screen 13h.

Who the hell uses that shit-ass mode?

PQBers . Faster than PSET, but slower than most libs.

[1000101]

PQBers are retarded ass-monkeys who need to learn how to code.

[KiZ]

Well done, youve just insulted the likes of the great QBers such as Optimus, and the brilliant democoders.

[1000101]

I wouldn't call anyone who is a PQB ass-monkey a 'great coder'. In fact, the PQB code I've seen from them has been anything but great. Most of it is slow, un-optimized and so hard to follow, they could at best qualify for 'ok coder', such as Optimus.

[Z!re]

I don't get what's with the "must have pure QB" thing.

QB is slow, if it can be made faster with a lib, then use it.


If YOU don't want to use a lib, then don't and shut up.


It's as simple as that. lol
