GSI-OpenSSH including High Performance NW updates

GSI-Enabled OpenSSH (Current Version 3.6 was released on Thursday, December 22, 2005):
　http://grid.ncsa.uiuc.edu/ssh/
　"NCSA maintains a patch to OpenSSH that adds support for GSI authentication."
　　　Grid Security Infrastructure (GSI):
　　　http://www.globus.org/security/
　"The current version of GSI-OpenSSH also includes High Performance Networking (HPN)
　 updates for OpenSSH from the Pittsburgh Supercomputing Center."
　　　High Performance SSH/SCP - HPN-SSH:
　　　http://www.psc.edu/networking/projects/hpn-ssh/
　　　Abstract
　　　"SCP and the underlying SSH2 protocol implementation in OpenSSH is network
　　　 performance limited by statically defined internal flow control buffers. These
　　　 buffers often end up acting as a bottleneck for network throughput of SCP,
　　　 especially on long and high bandwith network links. Modifying the ssh code to allow
　　　 the buffers to be defined at run time eliminates this bottleneck. We have created
　　　 a patch that will remove the bottlenecks in OpenSSH and is fully interoperable
　　　 with other servers and clients."

SSHを利用したファイルシステムとして sshfsというのがあります：
"Secure remote file management with sshfs", November 21, 2005
　http://www.linux.com/article.pl?sid=05/11/11/176206
　"But what if you need to work with files on a remote server, but find scp tedious in
　 repetition and FreeS/WAN too cumbersome? You might find just what you're looking for
　 in sshfs -- a tool for mounting a remote filesystem transparently and securely as if
　 it were just another directory on your local machine."
　SSH Filesystem:
　　http://fuse.sourceforge.net/sshfs.html
　　Abstract
　　"This is a filesystem client based on the SSH File Transfer Protocol. Since most
　　 SSH servers already support this protocol it is very easy to set up: i.e. on the server
　　 side there's nothing to do. On the client side mounting the filesystem is as easy as
　　 logging into the server with ssh."
　　　* Based on FUSE (the best userspace filesystem framework for linux ;-)
　　　* Multithreading: more than one request can be on it's way to the server
　　　* Allowing large reads (max 64k)
　　　* Caching directory contents
　Filesystem in Userspace:

これのパフォーマンスにも良い影響があるのでしょうか
