Since I see “top 10” lists appear everywhere, I decided to follow in line and produce my own top 10 posts of the year 2010:<\/p>\n
<\/p>\n
My view on things<\/strong><\/p>\n It is great to see what interests people the most. The number 1 post is also one of my personal favorites: It shows how snapshots (and especially removing them) can impact a VMs performance. I managed to get read performance down to 5% of the original<\/strong> while cleaning out a snapshot! It’s just a question of leaving no headroom for IOPs on a diskset which unfortunately is not unseen at customer sites.<\/p>\n Almost the entire “Throughput” series is also part of the top 10. Shame the final part was not read that much (Throughput part 4: A day at the races<\/a>) which covers a great hotspotting case on a storage array at a customer. You could actually see the “horse race” by looking at the activity LEDs on the array \ud83d\ude42<\/p>\n Also, a lot of people have read the introduction to the Sun OpenStorage performance tests we performed. Shame not too many people have read the actual report<\/a>. Ok I admit, 74 pages is quite some reading to get through. But ey, there are cool 3D surface graphs in there! I even sliced one up in this report.<\/p>\n
