[Gluster-users] Confusing lstat() performance

[Niklas Hambüchen]

I found the reason now, at least for this set of lstat()s I was looking at.

bup first does all getdents(), obtaining all file names in the
directory, and then stat()s them.

Apparently this destroys some of gluster's caching, making stat()s ~100x
slower.

What caching could this be, and how could I convince gluster to serve
these stat()s as fast as if a getdents() had been done just before them?
