How to browse LR Thumbnails as fast as MediaPro?

Question

i have a 100,000+ image catalog in both MediaPro and LR on a powerful Mac Pro
in MP, i can jump to any spot in the ENTIRE catalog & browse the thumbnails as fast as i can  hit the PageDown/Up button. in LR Grid Thumbnail Mode , it takes a few seconds or more before the thumbails are displayed, greatly slowing down browsing performance (unless the images were recently cached)
is there ANY way i can get LR to mimic MP's blazing speed in Grid mode when paging through thumbnails?
is there perhaps a way for LR to permanently cache all thumbnails at all times?
(i suspect MP can do this since it prebuilds a fixed size thumbnail)

Feel free to compare arch's shutdown procedure with ubuntu's and see where they differ.
For example, arch keeps it simple when teminating processes, it just sends a SIGTERM and waits 5 seconds for processes to terminate, then it sends a SIGKILL to everyone who may have refused to die and waits another second, so this always takes 6 seconds.
Ubuntu sends SIGTERM and then continually checks if all processes are properly dead every second for at most ten seconds. It then sends a SIGKILL to the remaining processes only if it thinks there are any. This means that if all processes are already properly terminated after, say 2 seconds, ubuntu immediately carries on with the rest of the shutdown procedure.
The arch method is KISS and in line with technical simplicity as defined in the Arch Way. The ubuntu method is inherently more complex and thus less ideal from arch's point of view.
If you really care about shutdown time you could port ubuntu's method to your own shutdown script.
