Code slows down my site, allot

[Kihon Kata]

Hi peeps. Need some help here. I'm running 3.5 here on it's own P4 3.0 dedicated server. I don't know if this is the correct forum to post this in, if not...then MOVE IT.

The site runs a bunch of different hacks/mods including trader ratings, vBA gallery etc. I have a modification that has my forum setup with ad collumns, both left and right. The left side colum is called from the header vB and the right side is called from the footer in vB.

When I edit my header and REMOVE the code that calls the left side ad column, my forum's pages load EXTREMELY faster. When I add it back, the pages load much slower. I really want to keep my ad columns but the slow down is killing my users.(BTW, I have removed the Adsense code and tried the speed, still the same slow downs without the ads)

Can someone look at this and gimme your best guess on why the below code is hammering my server.

Here is that code I am removing to speed it up:

 
<!-- BEGIN left AdColumns -->
<if condition="THIS_SCRIPT!=member && THIS_SCRIPT!=profile && VBA_SCRIPT!=gallery && THIS_SCRIPT!=gainaccess">
<table width="$stylevar[tablewidth]" cellpadding="0" cellspacing="0" border="0">
<tr>
<if condition="THIS_SCRIPT!=memberlist && THIS_SCRIPT!=search && THIS_SCRIPT!=showthread && THIS_SCRIPT!=editpost && THIS_SCRIPT!=newreply && THIS_SCRIPT!=newthread && THIS_SCRIPT!=usercp && THIS_SCRIPT!=private && THIS_SCRIPT!=forumdisplay">
<td style="width:130px" valign="top">
<if condition="THIS_SCRIPT!=tratings">$adcolumn_left<else />$swapadcolumn_left</if></td>
</if>
<td valign="top">
<table width="$stylevar[tablewidth]" cellpadding="0" cellspacing="0" border="0">
<tr>
<td style="width:100%">
</if>
<!-- END AdColumns -->

If you look inside that ABOVE code, you will see $swapadcolumn_left. so I thought I would display my code for the LEFT SIDE ad column:

 
<table cellpadding="$stylevar[outerborderwidth]" cellspacing="0" border="0" class="tborder" width="125px" align="center">

<table cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%">

In a nut shell, the slowdown of these codes are killing us. Any help would be appreciated.
