Hi, I understood and thought of your statistic comment once again. In the case of sampling, is there enough statistic to investigate?
In the case of a long SQL, I think that it is possible to obtain a sufficient sampling number.
However, in the case of about 1 minute of SQL, only 60 samples can be obtained at most.

Does this sampling number of 60 give information that I really want?
Perhaps it is not to miss the real problem part?
