In 2003 server,
1. Open Terminal Services Manager fullscreen maximized.
2. Display session status.
3. Press "Reset Counters".
4. Minimize to tray and maximize window five times. Here is a counters:
- without rdpcompression
- c0.png (14.27 KiB) Viewed 16616 times
5. Reset terminal and repeat with rdpcompression=on in config file. Here are counters:
- rdpcompression=on
- c1.png (14.84 KiB) Viewed 16616 times
Outgoing is traffic from server to client. The same frames counts mean experiment is quite clean: server sends similar amount of drawing commands both times. With rdpcompression=on we got twice less total bytes and twice less bytes per frame. Do not look at "compression ratio" line, it's another compresion level.
