The Best of the Week (Jan 16): Performance Zone

Make sure you didn't miss anything with this list of the Best of the Week in the Performance Zone (January 16 - January 23). Here they are, in order of popularity:

1. Getting Mutex Information from MySQL's performance_schema

• This is a short blog post to show how to configure performance_schema and get the info we need. The difference is clear. We get much more information from Performance Schema. In my personal opinion, despite the extra resources needed by Performance Schema, the change is for the better.

2. Performance Impact of an IO-Intensive Application

• If you’ve ever worked on performance issues with an IO- intensive app, there is a good chance you already know that the application performance degrades when the disks are stressed out. This fact is usually well known, but the reasons behind it aren’t always clear. I’d like to try and clarify what’s going on behind the scenes.

3. A Beginner's Guide to Java Persistence Locking

• In concurrency theory, locking is used for protecting mutable shared data against hazardous data integrity anomalies.

4. Minecraft Is the New Doom

This enables players who are aspiring developers to actually enhance the capabilities of the game beyond what the original developers had imagined. The idea of making things modifiable isn't new, but actually endorsing a tinker/hacker culture and finding ways to still make money on the product is commendable.

5. Improving Lock Performance in Java

• In this post I am going to share several common techniques you can apply independent of the tool used for detecting the lock.
