The NSE-1 was originally designed to try to improve throughput by using 
Parallel eXpress Forwarding (PXF), but the implementation of PXF seems to 
have been buggy from the start - to the point where it's common to hear of 
people running NSE-1s with PXF disabled.  In that case, the NSE is roughly 
equivalent to an NPE-225 in terms of packet forwarding performance.  The 
NPE-G1 and G2 are much more powerful in that regard.

Search through the archives of this list from this month and you'll find 
at least one other NSE vs. NPE thread.  You can get to the archives by 
going to the appropriate URL that's at the bottom of each message that
gets sent to the list.
