[OpenAFS] AFS and PhotoShop interaction?

[Mike Polek]

Hi, All,
   I'm not sure this is the right place to post, but I'm gathering
information and would like to know if anyone else has had a similar
experience. This is on Windows XP using 1.4.2a-DEBUG client.
The fileserver is running Fedora Core 5 and OpenAFS 1.4.2 (new machine).
Similar behavior using 1.4.0 and 1.4.1 windows clients and 1.4.1 fileserver.

   When opening images in Photoshop from AFS, they load rather slowly,
compared to opening a file on the local drive. This isn't unexpected.
However, if I open the file from AFS into another image viewer, it shows up
pretty much instantly. (This behavior is independent of which I do first,
and is repeatable, so I don't think it depends on whether the file is
in the cache.)

   Now the weird part.... If I copy some image files from AFS to
the desktop, and then drag them into Photoshop, they still load
slowly AND the CPU usage on the afsd daemon goes up to 50%.
Just seemed kind of weird that the afsd daemon gets triggered
after the files have been placed on the desktop.

   Anybody else notice any strange interactions between AFS
and photoshop?

Thanks,
