CPU

What is the difference between cpu utilization and load average for performance testing?

Cpu utilization reflects the use of cpu; load average reflects the fierce competition for cpu resources, the higher the incentive.

Cpu index mainly refers to CPU utilization, including user state (user), system state (sys), waiting state (wait), idle state (idle). Cpu utilization should be lower than the industry warning value, that is, less than or equal to 75%, cpu sys% less than or equal to 30%, and cpu wait% less than or equal to 5%.

Memory

The bottleneck in the system is mainly measured by the utilization of SWAP (swap with virtual memory) swap space. In general, the utilization of SWAP swap space is less than 70%. Too much swapping will cause poor system performance.

Disk Throughput IO

The disk busy rate is less than 70%.

Network throughput

Mainly refers to the number of M traffic per second in and out, generally not more than 70% of the maximum transmission capacity of the device or link.
