Subject: New threads within the router task

As mentioned before, the mail router has been enhanced in Domino 8.5 to include additional threads to perform specific mail routing tasks. These threads allow the router to process the work that used to be done by the one “main” router thread in parallel, which improves the throughput as well as reduces routing delays.

Each of these threads are shown as additional Router tasks in the “show task” output. Here’s a brief explanation for each.

A single router “Utility” thread performs periodic background work within the router.

A single “MailEvent” thread which receives immediate notification of new (or modified) messages in the server’s mail.box database(s). This thread allows the router to begin processing new mail as soon as it arrives on the server.

Multiple router “Dispatch” threads look at each recipient of mail needing to be routed, and determine how to get the mail to that recipient. This involves looking names up in the Directory (determine mail server/file), group expansion if necessary, DNS queries for outbound SMTP mail and using the routing tables to determine the next server to transfer to if necessary.

Multiple router “Sweep” threads perform post processing (after transfer/delivery), and may schedule retry or generate non-delivery reports for failures, and/or request that the mailbox threads update/delete messages in mail.box.

One or more router “Mailbox” threads, one per mail.box database. These threads read existing messages from mail.box on startup, and perform all update/delete operations for the router.

The router “Main” thread responds to “tell router …” console commands and coordinates the startup/shutdown processing of other router threads as well as a couple of periodic maintenance tasks…

Subject: Same here

I see the same on my server, but at the same time it is not explained in the help file or on boulder:[quote]Router optimizations – Router optimizations is a series of enhancements and changes to the Domino mail router designed and implemented to reduce latency, that is, to reduce the amount of time between when a message is sent and when it is delivered, to contribute to reduced I/O, and to address scalability issues caused by a large message backlog. These enhancements do not cause changes to the UI, but they are noticeable as performance improvements, new messaging statistics, and new router task detail.[/quote]
