Ticket #15195, comment 3
v2 v3 1 1 8GB for the VM. 2 2 3 Straight away when the VM boots and I run applications top shows heavy usage of resident memory. A bit concerning that this never shows directly in Windows. If it is the VM memory usage then it works in a very strange way I am not familiar with and achieves amazing results (some kind of deduplication or optimisation for empty blocks perhaps). However if it's able to do something like defer allocation for zeroed blocks I can't believe that there would be so many for one given the data I would expect to be in RAM and for the other restarting processes within the VM does not help much. If it is deduplicating it is doing remarkably well but there is no way I know of to get metrics on this. In that case the problem may be a weakness in that. 3 Straight away when the VM boots and I run applications top shows heavy usage of resident memory.

I don't see any strong indications that the memory usage of the main process strongly relates to what is happening in the VM. 4 4 5 5 KiB Mem: 8198436 total, 4269692 used, 3928744 free, 527576 buffers
