SharePoint performance monitoring counters
Well here we are at part 8 of my series on making SharePoint performance management that little bit easier to understand. What is interesting about this series is its timing. If by some minute chance that the marketing tsunami has passed you by at the time I write this, SharePoint 2013 public beta was released. Much is being made about its stated requirement of 24GB of RAM for a “Single server with a built-in database or single server that uses SQL Server”. While the reality is that requirements depends on what components that you are working with, this series of articles should be just as useful in relation to SharePoint 2013 as for any other version.
Now, if you have been following events thus far, we have been spending some time examining disk performance, as that is a very common area where a sub optimal configuration can result in a poor experience for users. In part 6, we looked at the relationship between the performance metrics of disk latency, IOPS and MBPS. We also touched on the IO characteristics (nerd speak for the manner in which something reads and writes to disk) of SQL Server and some SharePoint components. In the last post, we examined the windows performance counters that one would use to quickly monitor latency and IOPS in particular. We then finished off by taking a toe dip into the coolness of the SQLIO utility, that is a great tool for stress testing your storage infrastructure by pulverising it with different IO read and write patterns.
In this post, we will spend a bit of time taking SQLIO to the next step and I will show you how you can run a comprehensive disk infrastructure stress test. Luckily for the both of us, others have done the hard work for us and we can reap the benefits of their expertise and insights. First up however, I would like to kick things off by spending a little time showing you the relationship between SQLIO results and performance monitor counters. This helps to reinforce what the reported numbers mean.

The thing is my job isn't that hardby BeerWhore
After training I've been hitting my numbers like I've worked there for years. I don't have performance nor attitude issues at work.
Monitoring behavior at home would be an issue but I'm actually pretty chill to live with (so I've been told). I'm clean, I make nice food and share it, I'm actually pretty quiet.
There is the factor of my occasional wine/beer binge that I'd need to watch but that's not a bad thing.
Yeah, there are folks at work that would be assholes. And I'd worry that she'd try to "make an example" of me by making things harder on me just to show that I'm not influencing her
Sure. yeah, that's it.by peacewar
Better Interviews Said Key to Exit Polls By WILL LESTER, Associated Press Writer
Sat May 14, 6:39 PM ET
MIAMI BEACH, Fla. - Better training of interviewers to get a proper sample of voters after they cast ballots will be key to improving the performance of exit polls, one pollster who handled the 2004 election surveys said Saturday.
Exit polls on Election Day 2004 overstated support for Democrat John Kerry overall and in many key states, which led to widespread confusion that day about the election eventually won by President Bush.
The exit polls contacted more supporters of Kerry than of Bush because of "the failure of interviewers to follow the selection rate," said Warren Mitofsky, who conducted the exit polls along with Joe Lenski of Edison Media Research

ORLANDO, Fla. -- The lack of interoperability among traditional performance monitoring tools means data centers must use -- and pay for -- multiple tools. But movement toward unified performance monitoring could change all that.
