- The Performance & SQL coding at my company is only 50% as good as it was 18 months ago. We have Upgrade our processor twice within the past year.
- We had three processor upgrade within 18 month, the machine is still busy, transaction response time is poor, and the application rollout is even not finished.
- We were forced to go to Raid and SMS… Our transaction time have increased by 20%.
- We spent a week tuning we have increased throughout by more than 10%, and reduced elapsed time by more than 15%.
The people that made these statements did not want to be identified, nor have their companies made public. The basic message here is repeated at most of the companies we speak to – and the basics of performance rarely seem important to management; only getting the system up.
Get it up as fast as possible – you must meet your target data – we will tune it later. After more than three decades in this business, I am still waiting for ‘later’ to arrive.
