Description John Mazzitelli 2008-11-06 06:28:00 UTC

I have seen the agent's inventory sync go very slow.

I had an agent with about 180 or so resources.  I started the agent clean (nothing in /data directory; inventory.dat was gone). It took about 10 minutes for the agent to complete the sync - all that time, the agent showed red in the UI so this will be confusing to people thinking they started the agent but its not turning green within a minute or two from startup.

We need to optimize the inventory sync so it goes faster.

this was fixed for 1.2 release.  the old algorithm used to be O(N) where N was the number of nodes in the tree for that platform.  today's inventory sync is O(D) where D is the depth of the resource tree.

also, instead of creating and delivering measurement schedules one resource at a time, they are also bulk inserted.  alert template creation has been moved fully back to the server side.
