[NMLUG] M$ SFU v3.5 vs. Cygwin

[dlark at larkco.dyndns.org (Dan Lark)]

Just downloaded and installed M$ SFU (Services for Unix). (Hey 
don't shoot me, it is now a free download after all...) Firstly, I must 
say that I was impressed with the features it now has - most importantly 
better NFS/NIS integration. I also see they are now bundling what looks
to be a complete X11 system (this wasn't in the ancient version that
I had).

A couple of questions:

1. Performance - Do the Cygwin tools perform better/worse/same as the 
equivalent SFU tools? The reason I ask is that M$ makes a big deal of the 
Interix stuff hooking _directly_ into the Win32 POSIX layer (geez, that 
sounds like an oxymoron).

2. The NFS funcionality - Since the SMB protocol is very bloated, I am 
kinda curious to see if the NFS functionality that is in SFU would be 
better that what Samba/smbmount provide?

I would also be curious to hear other people's impressions of SFU.
