This might be off the cuff, but things to check out:

1) Check your transaction logs on SQL, if they are getting especially
huge, I have had apps slow down for me
2) Check your 'simultaneous actions' on the coldfusion server, be sure
it is set correctly.  Maybe you are having too many hits at once to CF?
3) Do you have free-form search options on your site?  Maybe a search
that is hitting a non-indexed field?  
4) Is this server running RAID 5?  Perhaps your drive is just
bottlenecking with requests
5) Try updating Java JRE to a newer version for Coldfusion, <shrug>
Might help!

Hope this helps at all!

Subject: MS SQL 2000 / Win Server 2003 Problem

Hi everybody... 

I hope this is the best place to post this.  I'm running out of options
because nobody seems to know what's causing this. 

I have a webserver... it's running Windows Server 2003 with all updates
except SP2.  It's running MS SQL Server 2000 with SP3a.  It's also
running CF MX 7. 

This server is running a series of personal websites and message forums,
on forum software that I wrote myself about two years ago.  There are
6-8 forums running off of the same codebase and database (the URL being
the determining factor as to what content is selected).  Ever since the
forums started getting a lot of use, the server itself has slowed to a
crawl.  It's a P4-3.0 GHz machine with 1 gig of RAM. 

I'm 99.9% sure that the slowness problem is being caused my SQL Server.
When I run PerfMon, I watch CPU utilization, Avg Disk Queue Length, and
a few others.  The one to note is Avg Disk Queue Length.  Whenever this
item spikes and maxes out, the system stops responding until the item
drops off again.  It seems unrelated to CPU usage.  These spikes last
anywhere from 5-30 seconds, and again while it's spiked, nothing else on
the server can take place.  In some instances, a remote session with
Terminal Services will freeze up; otherwise it just gets really
sluggish. 

These spikes go away if I pause or stop the SQL Server service.. but
that's kinda pointless since the sites won't run without it. 

There's only one database still in use on SQL Server now -- I've moved
the rest to mySQL, on the same box.  The one left is the big one -- the
one the forums depend on.  BUT, my users have said that the system feels
less sluggish now.  I've noticed it's not as bad either, but it still
happens. 

I would go ahead and move this last database, but the migration tools
for SQL Server to mySQL are poor at best, at least the ones I've found.
It takes several hours to export the data, and then several more to
manually modify the SQL code it exports because of bugs in the export
script that I've been unable to correct. 

So I'm kinda stuck and unsure what to do next... 

Any ideas?
