[FROG] route-map set metric

[Quentin Young]

Somewhat surprised you are seeing 7-8 second runtime as the default number of messages to process before yielding is relatively small at 1000. But yes, lowering that number via zapi-packets is appropriate.

Quite possible I am misunderstanding but it sounds like you're talking about redistribution, e.g.

This hidden gem looks like it might work crudely, but effectively.

zebra zapi-packets 250

Initial tests are promising. I can run out of memory on the tiny VM
before processes lock up or slow thread to death, so far so good.
