Big List of 20 Common Bottlenecks - High Scalability -
Hey guys - it's always awesome to see a listing of common bottlenecks, especially if you are new to some technology or environments. But it's also dangerous to use such a list as a crutch - or a replacement - to really being able to understand performance bottleneck root cause and resource utilization. http://mtomlins.blogspot.com/2012/04/bucket-full-of-bottlenecks.html Cheers, -mt Nice list, have
How long does it take to make a context switch?
