Both servers connected to the same switch, which supported 1 Gig, with Cat5e / Cat6.

I really don't know what could possibly cause that speed. I've read that maybe the 'auto-negotiation' configure may do it? Can I check what is the negotiated speed then somehow?

I'm using 'rsync -avzh --progress' command. my switch is hp v1910-48g. I also just tried to replace the Cat 5e cable to cat7, same speed.
