A bit off-topic - but IM and P2P Shield use zero resources by themselves - they are actually backed up by the FileSystem Shield and only allow for different (usually higher) settings / sensitivity for specific areas (those used by P2P/IM programs). So they are actually performance optimizations, and you certainly don’t need to speculate about any footprint of theirs - because there is none if no such program is used.
And, regarding the general footprint - it certainly should be smaller for version 5/6 than it was in v4, both in CPU and memory usage. Especially the updates were rather heavy in v4.x.
