thanks liquidat0r

but still waiting answer for any one who participated in creating both of it ...

i mean look

look at 1.2 features

Very fast loading.
Light on web server resources.
Doesn't output huge, non-valid, HTML pages.

does this mean that 1.3 dosent have that features or 1.3 is bitter in that features then 1.2

1. We haven't done benchmarks, so we don't know. But yes, I would presume that any difference in speed isn't drastic.
2. Yes
3. When it's done

And as Jansson said, enhancements are just that: new features to enhance what we already have.

Well... Adding new features DOES cost time processing. Always.
I.e., the simple fact of changing way of construct requests (which permits further modifications with hooks) IS slower than a 'plain text' request, but the difference is indeed negligible.
Another one : use of url_rewriting IS time comsumming (rather an Apache's issue, as the process of a .htaccess is not optimized), but the feature itself is real great..

And last but most important : the entire 'hook system' (which is the major benefit of 1.3) IS slower than the old ugly 'mod system' (since the eval() function is one of the slowest function in PHP, as it is in C or others).

So each 'extension 1.3' will be slower than the corresponding 'mod 1.2' (by construction)...
Hope it "isn't drastic", as u said..

why not try by yourself and chose the one that better suits you ?

Not necessarily.

I can't compare MegaPun, but what do you mean by "compare"? In terms of what>

Without Extensions (branches_punbb-1[1].3-dev-r1478)

checked every one of them 5 to 10 times before telling the finial result

index.php [ Generated in 0.009 seconds, 10 queries executed ]

Punbb Beta Test Forum [ Generated in 0.011 seconds, 6 queries executed ]

Test post [ Generated in 0.016 seconds, 7 queries executed ]

Profile [ Generated in 0.020 seconds, 5 queries executed ]

Search [ Generated in 0.014 seconds, 5 queries executed ]

Now Installing Extensions

following extensions will be installed

-Browser and OS icons v1.0
-Easy Profile Fields v2.0.2
-Last Post Subject on Forum Index v1.0
-reCaptcha v0.1
-Smiley List v1.1.1

with extensions

index.php [ Generated in 0.011 seconds, 10 queries executed ]

Punbb Beta Test Forum [ Generated in 0.013 seconds, 6 queries executed ]

Test post [ Generated in 0.019 seconds, 7 queries executed ]

Profile [ Generated in 0.022 seconds, 5 queries executed ]

Search [ Generated in 0.016 seconds, 5 queries executed ]

judging of what you said is correct .... if a little extensions like this effect that much i wonder how will the big ones react ... it also efftect the speed of page which is not even envolved in that extensions like search and profile pages

will test the 1.2 later ... i am tired now

They are also fairly meaningless figures. What actually matters is the time it takes from hitting a link or button to the time the finished page ends up loaded into your browser and thats normally a matter of perception rather than measured speed.

Concerning speed :
As elbekko and Paul mentioned it, it's not a big issue (as far as the extension itself is well done), and i didn't mean to say that...
And i'm not saying i'm against the 'extension system', on the contrary i'm thinking it's the best improvement of the 1.3.
BUT i reaffirm it WILL be slower (than mods), it's automatic, you can't get rid of that.

Well, it's rather easy to test : write just a couple lines in php (try i.e an array declaration and fill it with some random data), measure execution time, then embed the previous lines in an eval() and compare..

Mpok: That's not a measure of how the extension system slows things down though: you would want to measure PunBB pages both with hooks being used and without hooks being used.
SuperMAG: Those benchmarks mean very little. The scripts were .002 seconds slower. And you slowed them down using extensions that may or may not be efficient in the first place. And you didn't compare that to a 1.2 install of similar modifications. And how did you arrive at those final page generation times?
