Can you post the store proc and the actual execution plan (not estimated, so not retrieved from cache) for both a fast and a slow query if...

It's something SQL Server could optimise better internally when static parameters are being evaluated.
How?
There's one fundamental rule that the optimiser has to follow. Plans must be safe for...

Maybe, depends what kind of disaster. If the server is still up and SQL is still running and the log for that database is still available, you should be able...

Don't run profiler GUI on the server, run it on a client and point it at the server.
Don't run profiler GUI against a busy production server. Use a server-side trace...

The total size of a page is 8192 bytes. 8kB = 8*1024 bytes = 8192 bytes. So the number given in the course was slightly off.

Nick, what's the exact message you're seeing in the log? (obfuscate domain and DB names if you like)

Maybe SQL is detecting some type of corruption and is kicking of the dbcc checkdb to verify consistency.
SQL won't run checkDB automatically. It's a very CPU and IO...
