Just a very wild guess but I hypothesize that the 1/2 second delay is
due to virtual memory paging activity. LR is trying to do something
that requires more real memory than is available. It gets put on hold
while the OS frees more memory by paging something else out to disk.
Then LR suddenly has the processor back with the real memory it needs
and can run at full speed... pop... it's suddenly on the screen. Sounds
good to me because PhotoShop (and LR too?) has been known for many years
to be a memory hog.
Try doing the same thing with nothing but LR running. If still slow try
a smaller set of images and see what happens. If the 1/2 second delay
goes away you likely need more memory.
