Description

At this point, a few different people have reported seeing high CPU usage with funnels. Personally, I have never been able to duplicate it on a windows machine (I have tried on a few different boxes). Looking at some Linux VM's (running on top of Linux hardware) I have a cluster of 3 nodes. When adding funnels, two of the nodes exhibit the behavior but one does not. The nodes are (in theory) identical.

A coworker running Mac OSX has verified that he sees CPU usage of about 35% when adding a funnel to an otherwise-stopped flow.
