My system runs high on committed memory (out of 8GB RAM + 2 GB page file 85% memory is committed). Physical usage is at some 65%.
How can I identify what process(es) is allocating most of the committed memory? I understand that memory can be shared among processes. So far I've used VMMap to show committed memory but this is on a per-process base and doesn't take pagefile-backed sections into account.
