### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues. ### Description Doris use bit operation In `HashTableGrower` & `HashTableFixedGrower` to get buffer size like this: ```cpp size_t buf_size() const { return 1ULL << size_degree; } ``` The operation will be executed every time when `buf_size()` is called, but this is not necessary. ### Solution To remove unnecessary calculations, we can save the result in a newly added field. ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
