MySQL Verification Team
Hi Mr. Huang, Thank you for your bug report. We are quite aware of the impact that resizing of the buffer pool has on the specific mutex contention. However, we do not see how can that be improved drastically. Your idea of the manner of execution is very vague. Please, make it much more verbose and, if possible, propose to us a patch. Actually, a very detailed description of the new algorithm would suffice. Then we could make this a feature request. We are waiting for your feedback.
