Maximum

Scope

per-stack

Turn the scalable filter feature on or off on a stack. Takes one of the following values:

• 0 – Scalable filters are not used for this stack.
• 1 – The configuration selected in EF_SCALABLE_FILTERS will be used.
• 2 – Indicates a special mode to address a master-worker hierarchy of some event driven applications.

  The scalable filter gets created for reuse by port bound sockets in the master process context. However, active mode will become available in worker processes once they add one of the sockets to their epoll set.

  Applies to rss:*active scalable modes.

  Note: This mode is not compatible with use of the onload extensions stackname API.

If unset this will default to 1 if EF_SCALABLE_FILTERS is configured.
