Hi Felix,
If you already have a test cluster, please give me the gluster version.
I will try to build rpm then you can just do an upgrade. If you don't
have a test cluster, and you are creating a new one, then I will build a
new rpm against the latest head. This is more easier to me as I don't
have to backport to a previous version.
May I ask you the access protocol that you use (FUSE, SMB , NFS, gfapi).
I did the testing on a fuse protocol.

Dear Rafi KC,
lets suppose I going to spend some time for testing. How would I
install glusterfs-server including your feature?
Maybe this is an easy procedure, but actually I am not familiar with it.
Regards,
Felix

Hi All,
I have been working on POC to improve readdirp performance
improvement. At the end of the experiment, The results are showing
promising result in performance, overall there is a 104% improvement
for full filesystem crawl compared to the existing solution. Here is
the short test numbers. The tests were carried out in 16*3 setup with
1.5 Million dentries (Both files and dir). The system also contains
some empty directories. *In the result the proposed solution is 287%
faster than the plane volume and 104% faster than the
parallel-readdir based solution.*

Configuration
Plain volume
Parallel-readdir
Proposed Solution
FS Crawl Time in Seconds
16497.523
8717.872
4261.401
In short, the basic idea behind the proposal is the efficient
managing of readdir buffer in gluster along with prefetching the
dentries for intelligent switch-over to the next buffer. The detailed
problem description, deign description and results are available in
the
doc.https://docs.google.com/document/d/10z4T5Sd_-wCFrmDrzyQtlWOGLang1_g17wO8VUxSiJ8/edit
If anybody can help with the testing on a different kind of
workloads, I would be very happy to assist. If wanted to test the
patch and run a performance test on your setup, I could help with
back-porting the patch to the version of your choice.
