So I was telling my wife about this issue, and she had two interesting comments.

When I told her that the customer was complaining about performance, she stopped me to figure out what I meant by that. When I told her that they had to wait for 20 minutes, her response was:

Oh, I thought you were talking about 1/16 of a millisecond here again. Well, if it is 20 minutes, why make a fuss about it? They should go have a cup of coffee or something.

The second observation was when I told her that we narrowed things down to suggestions taking up a lot of a CPU:

Oh, so you told them to go and buy some more RPM, right?

My wife complained that her laptop was running slow. We had a discussion that went something like this:

Me: Okay, I think I know what is going on, this laptop has a HD with 5,400 RPM.
Wife: …
Me: …
Wife: …
Me: Okay, RPM is how fast the drive spins. The faster it spin, the faster it is. This is 5,400 RPM drive, and usually you want 7,200 RPM drive.
Wife: So go to the store and buy me another 2,000 RPM.

I was telling my wife about my day at work, and the conversation went something like that:

Me: So we spent all day trying to optimize this really expensive query.
Wife: What made it so expensive?
Me: We weren’t sure, but it run for 300 – 400 ms!
Wife: You are so impatient.
