I have Committed 7.0/18.2 GB and Cached 4.1 GB (if I use it together with Firefox, Media Player Classic and notepad), otherwise is it maximum 4GB.
With much more Bibles loaded.
And Yes, Compare and Parallel are also slow loaded on my computer.
But the copy and paste make no raise of memory on my computer.
Do you use Screenshot programs or multi copy and paste programs or smart key programs? If yes, turn them off.
Do the same test with Task Manager and Process. (without video capture)
Look to the active Apps and Background processes.
Is there any other App or Background process that use much memory or has above "Low" Power usage?
