[wp-hackers] Recent Comments Plugins.

"DreamHost support: I've temporarily disabled your database because you 
are running a query that is hitting the database too hard."

This is not the first time that we've had a "My host shut me down" post 
where a plugin is concerned. I'm sure I posted a while ago about this.
Given that these plugins will be used, and that some sites state that 
they are a good thing to use as they can increase interaction (I'm the 
messanger here, okay), then can someone advise as to which are the bad 
guys ? These are the ones I could find right now:

The vast majority of people whose use these do so in good faith and 
although there will be users who do daft things like display the last 40 
comments, and yes I know that some of these work differently to others, 
but those issues aside for the average user, which of these are the 
least likely to get a host shutting down a site ?
Or do I install each one in turn, run 10 comments through them while 
using the Query Diagnostics plugin and then rank according to time taken 
? I somehow think I'd get yelled at if I did that.
Any and all advice would be great.
