You may want to open your system monitor to see your memory usage. I suspect you are swapping out to your hard drive. On my system with 8 gigs of RAM working on a 640X360 frame uses up to 2.6 gigs of RAM for the OptFlow process. You may need to go down to 450X350 resolution to fit in your machine. On mine the reliable sets run 16 seconds.

Yes, that's normal. Especially DeepMatching needs a lot of resources. You can regulate DeepMatching by passing the -R <n> command line option to DeepMatching in run-deepflow.sh. This option allows you to downsize the input images by a factor 2^n (default: n=1). However, I have sometimes observed that non-default values for this option breaks the reliable set calculation. So have an eye on this if you experiment with that.

On the other side, you can also run the optical flow calculation in parallel, as I stated here: #9 .
