improved dot icons - decreases DB load

This Hack will decrease the Load on your DB-Server.
It adds one small Query to forumdisplay.php and modifies one big, slow query.
If you have lots of posts and $showdots enabled, this is a must.
If you disabled $showdots via Admin-CP because of performance issues, you can savely enable it now

Note: this will NOT work with PHP 3.x or lower

UPDATE: I've added instructions to modifiy member2.php, usercp.php and search.php

[Austin Dea]

Well, but that's all different code =P. I meant there can't be THAT many optimizations to vB2 without re-coding the entire thing

[Xenon]

ok, that's right.

you have to recode some things to optimize it

[Gutspiller]

Instructions say:

in MEMBER2.PHP

a) OLD CODE
--------
if ($showdots and $bbuserinfo[userid] >= 1) {
$dotuserid = "DISTINCT post.userid,";
$dotjoin = "LEFT JOIN post ON (thread.threadid = post.threadid AND post.userid = '$bbuserinfo[userid]' AND post.visible = 1)";
} else {
$dotuserid = "";
$dotjoin = "";
}
NEW CODE
--------
$dotuserid = "";
$dotjoin = "";

What I got:

if ($showdots and $bbuserinfo[userid] >= 1) {
$dotuserid = "DISTINCT post.userid,";
$dotjoin = "LEFT JOIN post ON (thread.threadid = post.threadid AND post.userid = '$bbuserinfo[userid]')";
}

$getthreadids=$DB_site->query("SELECT thread.threadid
FROM thread,subscribethread
WHERE subscribethread.threadid=thread.threadid
AND subscribethread.userid='$bbuserinfo[userid]'
AND thread.visible=1 $datecut $ignoreusers
ORDER BY lastpost DESC
LIMIT ".($limitlower-1).",$perpage
");
$totalthreads=$DB_site->num_rows($getthreadids);

if ($totalthreads>0) {

What do I do?

[pwr_sneak]

you could try to read the code and understand how it works :P
which vbulletin version do you use? if its not the latest stable (2.3.0), try to update it.

[sabret00the]

how many ppl installed this?

edit: check the forumdisplay
