Address review comments from previous patch. Also implemented abbreviations as substitutions in docs/doc/source/shared/strings.txt. NB: This doc still to be reconciled against existing install/deploy content. Restored fault/index version of FM toctree in top-level index. Removed Fault Management from top-level index. Initial review submission. Signed-off-by: Stone <ronald.stone@windriver.com> Change-Id: I76c2e99bd96bb1d58d6daf67ac46e6e48e4396d7 Signed-off-by: Stone <ronald.stone@windriver.com>

Worker Function Performance Profiles
|
|
====================================
|
|
|
|
|prod| 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.
|
|
|
|
|org| recommends the low-latency profile only for applications with
|
|
stringent latency constraints such as |MEC|.
|
|
|
|
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.
