Diagnose slow workspaces

Diagnose slow workspace runtime performance by tuning CPU and memory resource limits in your devfile.

Improve workspace runtime performance

Provide enough CPU resources

Plugins consume CPU resources. For example, when a plugin provides IntelliSense features, adding more CPU resources can improve performance.

Ensure the CPU settings in the devfile definition, devfile.yaml, are correct:

components:
  - name: tools
    container:
      image: quay.io/devfile/universal-developer-image:ubi8-latest
      cpuLimit: 4000m
      cpuRequest: 1000m

cpuLimit

Specifies the CPU limit.

cpuRequest

Specifies the CPU request.

Provide enough memory

Plug-ins consume CPU and memory resources. For example, when a plugin provides IntelliSense features, collecting data can consume all the memory allocated to the container.

Providing more memory to the container can increase performance. Ensure that memory settings in the devfile definition devfile.yaml file are correct.

components:
  - name: tools
    container:
      image: quay.io/devfile/universal-developer-image:ubi8-latest
      memoryLimit: 6G
      memoryRequest: 512Mi

memoryLimit

Specifies the memory limit.

memoryRequest

Specifies the memory request.
