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.

All of the escalations that have no pool defined will run in a random thread. For example, our 4th thread was defined for a custom notification-type escalation. It is the only thing that is assigned to pool 4 - but in the logs I see other threads accessing that pool - especially during those times when the escalation defined for pool 4 has died. B.

Where did you hear that pools are shared? According to the docs the only time an escalation specified to run in a pool (thread) will run in a different pool is if you don't define enough thread queues for the number of pools you are using. (i.e. You tell an escalation to run in pool 4 but you only have 2 escalation queues defined. The escalations set for pools 3 and 4 run in the first one instead). Escalations are delayed if another is running in the pool. Straight from the docs Escalations can be assigned to pools so the escalations from each pool run in parallel on separate threads within the escalation queue. To use escalation pools, you must first configure multiple threads for the escalation queue as described in the Configuration Guide, "Queues," page 27. If you assign an escalation to a pool that has no thread configured, the escalation is run by the first thread. All escalations in a particular pool run on the same thread, so the execution of escalations within a pool is serialized. Escalations run in the order of their firing times, but an escalation is delayed if an escalation from the same pool is currently running. If two or more escalations have dependencies and must not run at the same time, put them into the same pool to make sure they run in sequence.

One of our mission-critical escalations (interval, 5 minutes) will every once in a while die. It will stop appearing in the escalation log, and the only way to fix it is to bounce the admin server. There's 204 total escalations on this server, the vast majority of which are ITSM 7.6.04 base product. We are entering 4000-5000 tickets a day, with additional data being entered in CM, CMDB, etc., so the data load even for things like the 5-minute recurring SLM Measurement escalation can be significant. We have configured the one that breaks it to run on a specific pool and no others are configured to use that pool. Unfortunately that doesn't mean that pool isn't shared - others can hop in that pool too if the others pools are busy. (Kind of thinking of submitting an RFE for a "dedicated pool" option that prevents sharing but that's another issue altogether). So - how many pools do you use? We currently have a max of 4 and obviously that's not enough.
