DB2 for z/OS Performance CPU Regression

Hi Folks!

Aktuelle Unterlagen, unter anderem der neue Performance Guide zur DB2 for z/OS Version 8 sagen …

• Performance objective is less than 10% average CPU regression
• Typical customer workload regression is expected to be 5 to 10% higher on average
• This assumes no application rewrite and no aggressive configuration change to take advantage of V8 significant performance features
• 0 to +15% Online Transaction
• -5 to +10% Online Transaction in Data Sharing
• 0 to +20% Batch
• -5 to 5% INSERT
• +5 to +20% SELECT, FETCH, UPDATE
• -10 to +15% in Batch Data Sharing
• -20 to +15% Batch DRDA
• -10 to +10% Utility
• -20 to +15% Query

Gibt es Kolleginnen oder Kollegin, die bereits etwas zur Veränderung des CPU Verbrauchs der neuen V8 sagen können.

Ciao
