RouterAllowConcurrentXFERToALL

Parameter: RouterAllowConcurrentXFERToALL
Short description: Allows multiple concurrent Notes-routing transfer threads to destinations outside the local Notes Named Network (NNN) — including connections via Connection documents and into other Domino domains. By default, multithreading is disabled there.

Description

  • SMTP transfer in the Domino router is always multithreaded.
  • For Notes routing, multithreading is only active within the local Notes Named Network (NNN) by default. As soon as a connection requires a Connection document — typically for connections to other Domino domains — the router by default allows only one transfer thread per destination.
  • RouterAllowConcurrentXFERToALL=1 removes this restriction:
    • The server no longer checks whether the connection is fast enough or whether the queue contains enough messages.
    • Multiple parallel transfer threads are then also allowed to inter-domain destinations.
  • The maximum number of parallel transfer threads per destination is still bounded by MailMaxThreads.

Example

RouterAllowConcurrentXFERToALL=1
MailMaxThreads=4
  • Domino allows up to four parallel Notes-routing transfer threads per destination — also to other domains.

Notes

  • HCL recommends this switch only on servers with high bandwidth to the destinations. On slow WAN links, multithreading can degrade performance instead of improving it.
  • Change requires a restart of the router task (restart task router) or a server restart.
  • The effect only takes hold once MailMaxThreads also has a sensible value > 1.
  • Works on all supported platforms.
