Re: SQL Tuning question?

Hello,

I think, there are 3 factors in performance tuning:

• Time
• Amount
• Speed

Most imporatnt factor in performance tuning is the time. Of course others are important, too. But, others are indirect indicator. For example:

• 1 block 1000 ms
• 1000 block 1 ms

As we see above, second one takes less time although it gest more blocks. we can't say that problem is in second one(if there is a problem in one of them).

And,

speed is indirect indicator, too. nobody asks the speed of cars in formula races, but asks time spent in races.

I think, time is the most important factor. itrprof is based on time. you can run itrprof to see bottlenecks. it's at
