In my limited experience with MSSQL the best investment is improved Hard

As an adjunct to the advice you've already received (which is
excellent I might add), I always recommend looking at the business use
cases for reporting. Are these reports ad hoc reports or are they
known reports that you can schedule ahead of time, execute during off
hours, then save the results
Mike had a lot of good comments. How dynamic is your data? Is it constantly
being updated? If so, do you need real-time query results?
You need to balance the creation of indexes (as many as possible on a
relatively static server) with the fact that indexes can slow down
insert/update/delet
The Database Engine Tuning Advisor only gets you so far and some of
the recommendations it generates are bad recommendations. For example,
it might suggest redundant overlapping indexes. It currently takes a
human to properly set up indexes.
Your best bet is to find the bottleneck and try to quan
Hi. I have a SQL Server running on:

On a four core system, a CPU pegged at 25% means one core is at 100%;
CF has probably filled the JVM memory and is permanently garbage
collecting.
I agree with Dave - get FusionReactor and set a memory alert threshold
in the crash prevention options.

I suggest you invest in one of the other monitoring tools available -
SeeFusion or FusionReactor. You will likely find the problem a lot faster,
and it'll pay for it
Every since upgrading to CF8 I've been having a frustrating problem. After
starting CF, it will run for a while (sometimes serveral hours, sometimes

Grab a copy of seefusion or fusionreactor and watch the server especially
