Christmas Special: Free Stuff From Microsoft – TechNet UK – Site Home – TechNet Blogs #yam

Christmas comes but once a year, which is similar to the frequency in which I blog.  I thought as it’s the season of good will, I would write a blog that details some of the free stuff we have to offer.

Why Averages Are Inadequate, and Percentiles Are Great | Cloud Computing Journal #yam

Anyone who ever monitored or analyzed an application uses or has used averages. They are simple to understand and calculate. We tend to ignore just how wrong the picture is that averages paint of the world. To emphasis the point let me give you a real-world example outside of the performance space that I read recently in a newspaper.

The article was explaining that the average salary in a certain region in Europe was 1900 Euro’s (to be clear this would be quite good in that region!). However when looking closer they found out that the majority, namely 9 out of 10 people, only earned around 1000 Euros and one would earn 10.000 (I over simplified this of course, but you get the idea). If you do the math you will see that the average of this is indeed 1900, but we can all agree that this does not represent the “average” salary as we would use the word in day to day live. So now let’s apply this thinking to application performance.
