How often have you been stuck in traffic? In many cases, we slowly advance through the gridlock and eventually spot the offending accident or construction work, then off we go. What about when we see no problem? We slow down or stop (sometimes repeatedly), for no apparent reason, then resume just as mysteriously. Not understanding why, is often just as frustrating as the delay itself.

The z14 has vast throughput potential. With almost 200 Processing Units (PU's) and 32 TB of cache memory, this is a box designed for massive, parallel processing. So why do the same jobs sometimes take longer? Why do I need to turn on additional engines when transaction rates seems similar? Just as higher speed limits or more lanes don't always solve traffic problems, more MIPS or more memory is not always the answer.
In this session, John will share his insights from over 25 years of performance analysis. we will explore common sources of application delays and discuss practical solutions to reduce these delays. Stop the rage. Don't get mad; get moving.
