There is a patch to OpenSSH to fix the buffer size problem caused by the different operating systems OpenSSH runs on. When the host and remote are different operating systems the send/receive buffer sizes do not match and this causes drastic slow down. Like in using gentoo client connecting to a FreeBSD box or Linux box. ports/security/hpn-ssh/ contains the patch code to fix this problem in sshd/ssh.
