How Can I Handle a Slowdown in Disk Read/Write Speed and Increased I/O?

Symptom

If you are aware of a service slowdown, depending on if you are examining a Windows or Linux server, you can take the following actions:

  • Windows: Open Task Manager and view the average response time.
  • Linux: Run iostat -dx to view the I/O performance.

If the disk read/write speed is slowed down, disk I/O increases, or the await time increases, the disk is likely encounters a performance bottleneck.

Solution

It is recommended that you change to a disk type with a higher specification. For details, see Changing the EVS Disk Type
