Ok, that's strange because I've done very similar with the mass rebuild script I have and I was not able to create any sort of noticeable load on the server.  Certainly does sound like an ssh issue though.

Might have gone quicker if you pull via git:// and then only push via ssh:// reducing your ssh handshakes by half.
