i set up a new sql-server, ubuntu 18.4 (MYSQL 5.7), 24 core (48 threads), 256G RAM, System is SATA Raid1 XFS SSD /var/lib/ is mounted on Optane SSD XFS.
In restore i can see that the server has unter 1.0 load so it is quit sleeping. I dont know what i can improve to speedup the restore.
Dump size is 30 GB gzip about 160gb 300 mio entries, attached my mysql.cnfIt is a stand alone server just for mysql.
The old server ist mysql 5.6, i dont know if it is able to copy the ibdata files?
