Worker Function Performance Profiles
offers a choice of two performance profiles for worker hosts configurable at the Kubernetes platform level.
- Standard
-
This is the default profile, offering an optimal balance between throughput, latency and functionality. The standard profile is suitable for most applications.
- Low Latency
-
This profile is optimized for low-latency performance. Characteristics of a low-latency worker host include:
- lower throughput for most configurations
- higher power consumption at low CPU utilization
- disabled per-CPU scheduler watchdogs. This can result in increased fault detection time for some fault scenarios.
recommends the low-latency profile only for applications with stringent latency constraints such as .
You can create a heterogeneous configuration in which standard and low-latency worker hosts are mixed in the same standard deployment. Standard and low-latency worker nodes are identified with node labels. When launching a container, you can choose the required performance profile by specifying the appropriate label in the node-selector.
