When the index pipeline begins backing up at any stage, which resources are responsible for the bottleneck. Obviously, once backed up the problem will overflow into other areas but is there a "rule" or anything that says if the backup is at the Parsing Pipeline then the storage IO is too low, Merging Pipeline then the CPU is too low, Typing Pipeline the memory is too low, or Index Pipeline it's network bandwidth, etc. I am specifically looking for info regarding a Heavy Forwarder but any help would be appreciated. *It's not as bad as the picture makes it seem, just posting for visual*
