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
