[OpenAFS] performance stats
Fri, 28 Sep 2007 13:39:55 -0700
I think this gets beaten every six months, but I wonder if there are
any current metrix that compare openafs and cifs when working on
standard 'office' style documents. I'm interested in performance on
subsequent open of same file
I know there is huge variability between applications so that a Word
document may open much fast than a wordperfect doc... so this type of
measure may not even be possible to make accurately.
I'm just curious if anyone as tried, and what the results were.
We are finding that cifs performance is very BAD over a WAN and I'm
guessing that the checkpoint vpn software the we MUST run is a
contributing factor. We can't trust cifs over the wider internet
without vpn. We can trust afs. But there are still some microsoft
diehards that just don't think anything else could work.
My assumptions are the afs should perform better becuase
1) we don't need to tunnel through a vpn
2) cache manager should make these work better over a WAN where we
don't control the end to end bandwidth -- i.e. over the commodity
Since we need to support roaming faculty that connect in hotel
lobbies, conferences, etc., we need something that is going to be
fairly tolerant of changing network conditions.
