Heh, this seems to be becoming thematic for my posts in the thread...
Anyone around here worked much with Extended Events? It's way out of my scope, I only know the name.
If you have, would you mind poking at here:

OK, my interest is piqued.
But my understanding of the desired solution makes me think this may not be a well thought out application of XE. I'll fiddle with it.

When someone has a basic (not as advanced as intermediate) understanding of a foreign language they will struggle quite a bit with stuff like SQL Server manuals - it's inevitable. Mostly people end up with a reasonable grasp of technical English which they gain at the same speed as they gain an understanding of SQL Server (although they may remain pretty incompetent at handling English not related to database technical things, and often - unfortunately - don't learn to forulmate things in English as well as they lear to understand them).
This poster is evidently at an early stage of the process. It's not scary to see someone at that stage. It is a bit scary to see that [s]he's expected to communicate with dev, test, production and users and needs to come to SQLServerCentral for help rather than geting it in house.

[quote]If his machine is as underpowered as my desktop, it will take approximately 40 minutes to gen a billion rows. I know because I tried it a couple of years ago.
I'll generate a billion row table and see how long it takes on my (definitely underpowered) machine.
Well, it seems my machine is quite a bit slower than Jeff's. Of course I can gen a CTE which appears to have that many rows (that's how many is says it has if you count them) in a lot less than 40 minutes (actually in a lot less than 40 seconds), but producing a table with a billion rows takes a lot longer than 40 minutes
On various approaches to generating a billion rows, I either find I don't have enough filestore to get there (either tempdb blows up, or the db which will contain the resulting table blows up, or both) or I have to split it down into small batches and it takes insane amounts of time. If I assign (and hence initialise) loads of empty log pages in advance, the time is reduced by about 35% (exactly how much varies according to which method I try of generating the stuff). Writing into a table with a primary key seems to be slower than creating a heap, but not much. Extrapolating from how long it takes to generate smaller chunks using all the available disc space and then checkpointing and dropping temprary stuff to get some back suggests that the best approach on mu machine would take not 40 minutes but rather more than 40 hours. I guess that's the trouble with using a laptop that was intended to handle email and act as a client to proper SQL Server machines - now that I no longer have my servers and my desktop machines, the little toy is easily overwhelmed.

I should try to gen a billion rows for giggles. I got a new workstation, Win 8, 24GB ram, quad core, 4TB. Might be interesting.

Let's see who can gen it faster...

Of course "Set", you wouldn't want to generate these are RBAR, but who's Mark?

When you encounter a problem, if the solution isn't readily evident go back to the start and check your assumptions.

Another crazy snowstorm in Kansas City. This is the second thunder snow in 5 days. It is really quite odd to hear rolling thunder while it is blizzarding. We got a little over 12" on Thursday and they are predicting anywhere from 12 - 20" overnight and through tomorrow. Yet another forced vacation day tomorrow. See you all in a couple days once we dig out again.
