RDP (specifically with Windows as the desktop) is integrated into the display pipeline such that it effectively never loses frames. The results of an (e.g.) Excel redraw over a slow link can be spectactically stupid with every cell being drawn each time it is "re"-computed. The result is that the application itself is blocked when the RDP frames are being generated.
I/we observed this a decade ago when building virtual desktop infrastructure. There was a Linux Xrdp server (via a bunch of patches that didn't survive) that was more screen-scraper. VNC has always screen scraped the pixels, so it "naturally" skips the intermediate frames when the application draws faster than then remote desktop protocol can keep up. I thought that there were patches to RDP to make this better, but I never confirmed this. _______________________________________________ Bloat mailing list Bloat@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/bloat
