Re: How many escalation pools do you have...?
One of our guys is currently analyzing this - in short, everything we don't really use will go on 1. Stuff that is scheduled and won't conflict will go on a couple different ones. The real problem is the interval ones. Those we will split out into a few more threads - probably 6-8 total.

Re: How many escalation pools do you have...?
WOW nice to know. We have a very powerful production server and now we increase our Escalation threads. Not sure why I thought it was restricted to just 4 but 30 now that is impressive. Thanks for everyone's replies, It has really opened my eyes as to what I can do with Escalations and the number of threads we can add.
