hi,
i'm using mysql 7.1.15 on two linux servers in a cloud.
when restarting a node or when adding a new node, i see that the servers is almost idle(disk io is low, network load is around 15KB and cpu is around 99% idle).
it also happened when loading a csv file into a table, it took more than 10 minutes while doing it on a single mysqld(no cluster) took 30 seconds, and again the server was almost idle.
so i just want to know why doesn't the servers use more resources ?
thanks.
