Or clear statistics :) Massive data growth can change a sproc's best intentions over time.
Placing select top 10000 in your query was good for testing speed but could lead to missing rows that you need over time.

With MSSQL it's all about execution plans and statistics. An SP is a known quantity whereas SPT queries have to be evaluated each time they are run. Regardless, a poorly written SP or one with a bad plan in the cache can still perform badly. As Uncle Ted always tells us, you have to test in your environment with your data.

I always thought stored procedures were faster??

There are performance implications to using SPs, at least in MSSQL.

Why would you NOT use sprocs is my #1 question?
Years ago there was the debate as to whether you put all the logic into
your backend database or DataObject class...I went for the latter. Gave me easier portability if I ever needed it. (And actually, I did...I went from VFP backends to MySQL/MariaDB 15 years ago. Required VERY LITTLE code changes!) Now that doesn't mean I don't use stored procedure...I do! I just don't use them for basic INSERT/UPDATE/DELETE statements. I do use triggers though too.
