How Can I Handle a Slowdown in Disk Read/Write Speed or Increased I/Os?

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 to encounter a performance bottleneck.

Solution

Method 1: Change to a disk type with a higher specification. For details, see Changing the EVS Disk Type (Beta).

Method 2: Create a new disk from a disk backup to retain the disk data. The procedure is as follows:

  1. Create a backup for the disk.

  2. Create a new disk from this backup. During the creation, select a new disk type and configure advanced settings (sharing, SCSI, and encryption) based on your service requirements.
