If it's soooooo easy, why have less than half got it right?

Maybe because whoever got it wrong are not familiar with the Resource Governor basics.

Nice question Steve! Had to do some research to get this one. The formula totally makes sense and is easy enough to actually memorize. :-)

Perhaps we got it wrong for exactly the same reason that using such minimum settings is a bad idea in many cases. SQL Server will hold the sum total of MIN setting idle if those pools with the MIN setting aren't being utilized. Therefore, if you have ten pools (pool1 through pool10) that HAVE 10% MIN and 100% MAX, and all pools are sitting idle until pool4 gets a big load, 90% of your resources will remain idle while pool4 struggles to handle the load with only 10% of the available resources.

Yes, the example is extreme, but so is the waste made possible by (mis-?)using this feature. The rationale is that a long query could tie up the resources for a while if allowed to utilize another pool's MIN amount, so it must sit idle when that pool isn't using it.

It's only easy for people who have some idea how resource pools work. Most people make no use of resource pools, and a lot of those who don't use them (and some of those who do) don't bother to learn about them.

Easiest three points ever. That much closer to using my points stash for retirement.
