Performance

These actions can enhance your system performance:

• Enough CPU and memory are allocated to the agent (see resources). See the your Kubernetes monitoring software to detect bottlenecks (notably CPU, RAM, IOPS, network, disk size).
• No emptyDir is used (see pipelines.cache.volumeEnabled, pipelines.tmpdir.volumeEnabled, and extraVolumes).
• SSD volumes are used for both cache (see pipelines.cache) and system temporary directory (see pipelines.tmpdir). For exemple, in Azure, the managed-csi-premium volume type is a high-performance SSD.
• The network bewteen Azure DevOps server and agents has a low latency.

BuikdKit specifics:

• Choose an ephemeral disk for the cache in /app-root/.local/share/buildkit, instead of an emptyDir.
• Use an high-performance disk for the cache, exemple managed-csi-premium in Azure.
