[9fans] Scalability

[9fans] Scalability

[Kris Van Hees]

Has anyone done any work on researching the scalability of Plan9?  What I am
trying to look into right now is to get a handle on how well the distinct
services scale (since the entire distributed architecture scales well by its
very design).  E.g. if you set up a fileserver, either the older style, or
using fossil+venti, how many users/storage can you realistically support before
possibly needing an additional fileserver to offset the load.

 From Sean Quinlan's Venti paper, the Bell Labs has been supporting 50-100
active accounts at roughly any given time.  Is there any data or theory on
how things would be affected if e.g. you'd want to support 1000 or even 10000
users on a Plan9 infrastructure?

Greg Watson has tested u9fs here with 1023 clients on the Pink cluster.
This is u9fs with a few mods for scalability, and the v9fs VFS for linux.

The 9p2000 protocol is really excellent and should, it seems, scale far
better than others.
