If your mysql server is taking 6 hours to alter a 1.5 million records User table, then its badly broken.

Paul, no. You can pm Zachery for my server admin company if you like and see his reputation on WHT, I don't think you will argue your point with an expert. Or may be the misunderstanding is coming from me? There was a lot of changes, tables gets locked to safely finish the changes and thousands of changes does take time. I've seen it in the logs.
People just keep saying stuff that they have no first hand knowledge of.
Like I said try any of DB's plugin on with big sites that have million of threads, posts, and registered members and see how fast your will finish important the xml. You can share the result later if you like.
