Hi, Peter
Thanks for reply.
With following setting provided in bug 93734, the write-only perfomance of mysql8 improved about 10~20 for difference cases.
For sysbench readonly suite on mysql cluster (one primary, 2 slaves), we find there are 30% degrade. Do you have some bug/link that talk about it direclty, so that I can refer to make some configuration change (on /etc/my.cnf)?
