Tuning Performance Mode
To tune performance mode for the traffic, you can specify the number of Workers dedicated to processing multicast and control traffic. You can specify any value in the range of 0 through 15. The default of 0 specifies that all available Workers are used to process all traffic.
The number of dedicated Workers specified in relation to the number of available Workers results in the following behavior:
If the number of dedicated Workers is greater than or equal to the number of available Workers, then all available Workers are used to process all traffic.
If the number of dedicated Workers is less than the number of available Workers, then the first set of available Workers (equal to the specified number of dedicated Workers) is used to process multicast and control traffic while the remaining available Workers are used to process flow cache traffic.
To specify the number of dedicated Workers for processing multicast
and control traffic, configure the number of Workers at the [edit chassis fpc 0 performance-mode] hierarchy level.
[edit] user@vmx# set chassis fpc 0 performance-mode number-of-ucode-workers number-workers
Changing the number of Workers reboots the FPC.
