hpn-ssh is a very good solution Along with network buffer tweaks, I routinely use it on BSD, Solaris and Linux hosts over long haul private gig and 100meg links to approach the speeds one can achieve with rcp or rsyncd. It may not solve your CPU pegging, but in practice where such issues do not exist, it takes a minute for the sending host to prime the pipe. The settings I begin setting higher than the defaults are: net.inet.tcp.sendspace net.inet.tcp.recvspace net.inet.tcp.recvbuf_max net.inet.tcp.sendbuf_max There are likely more settings to change and I'd be interested to see them.
