Ok, Justin MacCarthy pointed out something for me to try. He suggested
using count(cfid) instead of count(*) which would yield the same results.
This table has like 944 records btw, here are the results of time in ms
taken to run 1000 queries of each over 5 tries:
Using count(cfid): 3313
Using count(*): 3422
Using count(cfid): 3297
Using count(*): 3140
Using count(cfid): 3281
Using count(*): 3141
Using count(cfid): 3281
Using count(*): 3187
Using count(cfid): 3281
Using count(*): 3141
Hmm, the first try came out how I expected, but the other four leaned
towards count(*). But really, 100 ms difference over 1000 runs is truly
insignificant, that is 0.1ms per query on the difference. So, count(*) and
count(column) is handled the same at least in SQL Server. If anyone has an
Oracle or other DB server running, I can pass the code along for running
this test over again.

Subject: RE: count() or recordcount
Just ran a test using my CGLOBAL table that holds client variables in an
ODBC database. Over 1000 loops of a query grabbing cfid and using
recordcount, it took 20031 ms of time. To get the recordcount using the
count(*) method, over 1000 loops of the same table, it only took 3406 ms.
So, if you are only interested in the amount of rows, count(*) from SQL is
much better, but in most cases, you want data and a recordcount, there I
would use CF's RecordCount variable.

Which is faster? I'm presuming count() or what else would it be good for?
