Hi Mr. chen, Thank you for your bug report. However, we can not process further your report. First of all, you have not made comparison with our current release, which is 8.0.27. Performance tests (and all other bug reports) are always supposed to use our latest bug-fix release, which for 8.0 is currently 8.0.27. Next, you have not configured our server for the maximum performance on OLTP test. Just setting the size of the InnoDB buffer pool does not suffice, since there are hundreds of variables that could be tuned for optimal OLTP performance. We accept bugs without optimal configuration, but we do not accept performance deterioration reports that do not use optimal configuration. Last, but not least, you should use our binaries, which are built for both speed and stability.
