I have had the opportunity to go through the first three SQLSkills Immersion Events, and one of the side benefits of that is getting to meet and interact with their team. One of their team that I never really even knew of before he joined SQLskills was Joe Sack, and (like everyone at SQLskills) he is just too smart (It isnt fair!) :)
He has a great new article up on SQLPerformance.com about "Troubleshooting SQL Server CPU Performance Issues" and while it may seem like basic stuff it isn't - CPU issues are not something every DBA deals with every day (Memory and IO issues yes, but CPU not so much) and he describes a good framework for where to look for information and how to get started.
I don't think for a minute that there is anybody reading my little blog that doesn't already read the SQLskills blogs, but I wanted to draw attention to this because it isn't a SQLskills blog. SQLPerformance.com is a dual effort between SQLskills and SQL Sentry, and their blogroll is crazy-talented:
Make sure to check it out - a new article comes out every week or two, and the content is top of the line. You won't regret it!
