[Dav-linuxfs] Slow and strange behavior

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hello,

When doing an "ls" in a davfs mounted file system I noticed it was very
slow. I checked out the latest snapshot from CVS and I turned debug on.
I perform an "ls" in the root of the mounted directory and I get the
following output:

-------------------------------------------------------------------

It continues on for serveral more strange attribute requests before it
does the correct one. On the webdav server (apache with mod_dav) I get
the following in the access logs:

Now, Where are all these strange requests coming from for ls and i686
and mmx etc. the "ls" would be much faster without all this of course.

Thanks,
