Re: QZDASOINIT prestart job tuning

[Evan Harris <auctionitis@xxxxxxxxx>]

Hi Chris

I've changed the initial number of jobs in the past, and seen other
customers do this as well, in order to get the preferred number of jobs
activated as part of starting the subsystem. At one customer it was set to
3,000 but I bet there are others out there with significantly higher
settings.

I'd set the number of  jobs at around 750-800 maybe even a little higher in
your case (say 850), particularly if you are going to change the maximum
number of uses to 1. In that case you would want a job available for new
connections as they connect rather than having them delayed while a job
starts up.
