Ok, what this Hack does is it reduces the ammount of queries on forumhome by caching the moderatorlist and by optimizing most of the queries used on index.php


I'd really appreciate getting feedback how it reduces serverload on greater boards

On an unhacked vb index.php (pm enabled accesmask disabled) it reduces the ammount of queries from 19 to 15
my experiments have shown, that the queries are faster than the normal ones, too....

So, i think your assumption is not correct.
It is faster for users with few pm's.
where's the threshold of this considerable amount?
I do like those well scaling solutions more than those with unneccesary performance breaks.

I just wanted to say that it's not always good to run less queries than others do.

Maybe someone could figure out how many PMs are needed to make this one query slower than the original three.
My Database stores 1.3 million PMs and as I said before, the three queries are faster by factor 6 - 8

Exactly.

you are right here, it would be intresing to find out how much pm's are needed to slow down...

in all my tests the one query was faster, but i never had 1,3 million pm's which i think most of the admins won't have....
If you have such a great db and board the optimization is to diasble pm-queries at all...

the 3 pm-queries on index.php run 0.0068 seconds on my servers. no matter how huge the privatemessage table is since mysql doesn't have to read anything from disk or crawl through big B-Trees.

You're welcome seby

Hmm unfortunately, i don't have much free time, so i think i can't work on a new version of the hack.
Haven't taken a look at 230 yet.....

But i'll try to do what i can
