  https://docs.cloud.google.com/compute/docs/disks/performance The following tables show IOPS and throughput limits for regional Persistent Disk. These conditions apply to the stated limits: Achieving the stated limits requires a compute instance with at least 64 vCPUs and an N2 machine type or an N1 machine type running on the Intel Skylake or newer CPU. Instances using other machine types, such as N2D, have lower performance limits.

  OLTP D/B performance is depended on IOPs. SSD is the best solution for higher IOPs. In GCP bigger the disk size higher the IOPs.
