Is it Intraframe or Interframe? I think XAVC-S in the A7S is H.264 Interframe, which is Long-GOP. Not good for post. Transcode it to something with less overhead, like DNxHR or ProRes, and I bet the system will respond much better.
It shouldn't mater what the stupid codec is. If you're in single thumbnail mode, they should generate the thumbnail once and then cache it. The only time it should be re-rendered, is if it's been modified in some way.
I heve to admit that I kinda agree with this. Just a few KiB (on bigger projects a few MiB) wouldn't hurt so much for caching unmodified clips, then update the thumbnail when the clips get modified or every t time or on project open and cleared on project close.
EDIT: Actually now that I think about it, all it takes to optimize this is to let the thumbnail generator wait while the clips are in playback and start to generate them while nothing is in play. Like the continuous thumbnail one.
