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 On 27/05/2020 07:56, RAFI KC wrote:
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. https://review.gluster.org/24469 https://review.gluster.org/24470 Regards Rafi KC ________ Community Meeting Calendar: Schedule - Every 2nd and 4th Tuesday at 14:30 IST / 09:00 UTC Bridge: https://bluejeans.com/441850968 Gluster-users mailing list Gluster-users@gluster.org https://lists.gluster.org/mailman/listinfo/gluster-users
