Hi Cody,
The idea behind the new poller is load control.
With the old poller you couldn't control the load, if you had a lot of hosts it will just start a poller every 3 seconds and if the poll took a lot to finish that created high load.
The new poller runs N number of threads at the same time and distributes the work there, so you never run more than N polls are the same time.
It also should be faster because of less context changes, since a started poller child will poll more than 1 host in its life time.
With 200 hosts you should use around 30 threads, I'm not sure if a P3 500 will handle that. You should think on using SCSI drives and putting the DB in another server to avoid locking.
Hope that helps.
Javier

What are some of the benefits of the new poller? Does it reduce cpu and memory consumption, etc. We are using 0.8.0 with the old poller and things are working great. We currently only have 31 hosts with 396 interfaces, but will be adding a lot to that in the very near future. Our server is a Dual PIII 500 with 1Gb of ram. When we we have 100 - 200 hosts does it benefit the server performance to go to the new poller?
