RSS makes site slow

[Alpha52]

Well, when I try to make an RSS feed block, it works 100% fine but it makes it so that when I try to load a page it just keeps loading and loading.
But this doesn't happen all the time, only after a few page changes.
It's as if the RSS feed is trying to update maybe ever 10 seconds and the update lasts about 10-20 seconds.
That is just a theory though.
It only seems to happen on these Warhammer Online RSS feeds though but I have seen tinyportal sites with those exact feeds in blocks working fine. http://herald.warhammeronline.com/warherald/RSSFeed.war

Any suggestions?

RSS Feed has always slowed pages loading some , .. some feed more that others , I also believe it has to do with the server providing your site the actual rss feed..

Yes, RSS feeds are totally dependant on the "sending" end of the data.

Ya I figured that.
It's just that that one place for RSS is the only RSS that does this for me.
It's a drag really because it's the only one I need =/
Thx for the quick response guys!
