Slow website because of CB component(?)

Dear CB-Team!

I have two websites which have extremly slow landing pages since 2 or 3 days (needs 15-20 secondes to buld the site. The subsites works fine.)
www.sinnlichemassagen.org
www.tantra-massage-portal.com
I integrated a user search on the landing page with a code like this:
{component}index.php?option=com_comprofiler&task=userslist&listid=231&searchmode=1&Itemid=126{/component}

When I remove this code the landingpages starts in a normal speed. Did I call up the same searching component seperatly it works also fine:
www.sinnlichemassagen.org/mitglieder-schnell-suche/userslist

This happens since 2-3 days without any changes at both sites!
They are hostet at the same place. Could it be a server issue?

Joomla 1.5.26
CB 1.8.1
CB Subs 2.0.2

Thanx for your support!
Michael

I would say your issue is not with CB, but with the extension you're using that's trying to load a component inside of a Joomla article using some sort of component tag. Just create a Joomla menu link to your userlist and set it as your homepage. You should also upgrade to CB 1.9 as your install is out of date.
