I have 64 GB of memory on my system; It would be nice if Lightroom could use some of it (PS does) to improve performance

I have LR 6.11 (not cc) and generally a high end system (SSD disks etc) and LR is still very slow. (LR barely will use 25% of the system under the heaviest loads) but is still very slow.

Please can we get LR to take advantage of the resources available to improve performance
