Oh sorry, I thought I had posted that here but in fact I did so in a
different issue regarding getdents() performance (bug 1478411).

My benchmarking data set is trivial: 100k empty files.

In a directory on your gluster mount:

  seq 1 100000 | xargs touch

I found this simple benchmark data set (and even 10k empty files) to
exhibit the same lstat() problems as my directory with 1M files "real"
work load.
