Ever wonder about the performance consequences of these changes? What's better? What's worse? By how much? During today's quick commercial break, DBI demonstrated how you can now easily compare database and SQL workload performance, for two different time windows, in as few as two mouse clicks!!! DBI's Brother-Panther® can vividly show you the performance differences between any two different time periods. - Is CPU utilization up or down?
- Are transaction response times faster or slower?
- Are SLAs being met more frequently or less?
- Which SQL are running faster? Slower?
- Which SQL are consuming more resources to run? Fewer resources?
If you seek answers to these questions, DBI has a solution! Don't settle for OEM "free " tools from your database vendor - this is part of a conspiracy to make sure you buy more hardware than you need! In fact, DBI offers a long list of competitive advantages: DB2 LUW Performance Tools ComparisonOur #1 Job is helping you look great!
