Lightroom 6.7 und 6.9 only uses max. 4,194,303 kBytes RAM under Windows 7 64Bit.
When it reaches 4,194,303 kBytes RAM it becomes slow.
The Computer has 32 GByte memory!

I'm running Win/10 with 32GB memory and LR CC, not seeing that limitation.

I can't confirm that. I'm using Windows 7 64bit and my Lightroom 6.9 CC currently uses a little more than what you say. It's not much, but more (and it isn't slow either).

If LR uses more RAM, loads of people write in saying LR is a RAM hog - using far too much of their memory!! It seems Adobe can't win on this one. ;)

Perhaps we need an option as in Photoshop, to set the maximum memory we want to be available to LR.

Well, the memory consumption does seem excessive. This was after running LR for a couple of hours, doing not much else than processing a few files (no HDR/pano merging, no external edits).

If LR uses 1GB of RAM at the beginning of a session and >4GB after running for a few hours something does seem "off" - I don't understand the inner workings of LR so I'm not saying "memory leak" here of course.
