thank you! i'm using it on a lenovo T61p; it definitely feels faster.

First off, I really am a big fan of filesystem interfaces as used in Plan
9 - after all my PhD work was based on the model :)
My objective here is to debate and understand how the points made in the
paper relate to the Plan9 networking model.

Hi,
I've gotten mailfs to work in plan9port with gmail's imap service, and
now I'd like to get smtp working so I can reply. Has anyone tried
this? Is there a way to do it? How about configuring Acme Mail to use
something other than marshal (say, mutt)?
Thanks in advance,
Jorden

there is a mechanism.
user programs call read(2).

I've just pushed out kernel sources and binaries to incorporate
Aki's mtrr and vesa changes. The combination makes monitor=vesa
run quite a bit faster; we saw a factor of three speed improvement
in one case.
It's still limited to a single processor, but we've got someone
investigating ways to fix
I forgot to mention one incompatible change in the
new kernel source: the cpuid function now takes different
arguments: a function code and a 4-word array in which
registers ax—dx are returned.

i think that essential strategy is a winner. upas would use

Interesting read:
http://cacm.acm.org/magazines/2009/6/28495-whither-sockets/fulltext
If I am right, the filesystem based networking interface offered by Plan 9
has the three limitations discussed here:
* performance overhead: app requesting data from a socket typically needs
to perform 2 syste
With mail2fs I leave messages alone and use all kinds of mail lists
that contain just relative paths to actual messages. Perhaps nupas
could do the same.

I think I've mentioned this before, but on a few of my synthetic file
systems here I'm using what you describe to slice a database by
specific orderings. For example, I have a (long) list of resources

Hi John,
it took me sometime to go through the old backups but it seems
that the NFS setup is gone by now. You can still ask questions,
if you want to, but I won't be able to send you all the working
conf. files.

I am going to try Linux on the same noteboot with the same mouse. I
will inform you.
The same mouse works without troubles in the other computer with
WinXP.
