Sage, It is really great to have a performance meeting running. We'd like to join the meeting. So far, we have a list of topics that can be discussed on the next meeting(seems we already have many topics listed here, and its PRC holiday next week). * Full SSD setup performance limitations * Cache tiring optimization proposals * EC Performance enhancement Thanks Jian -----Original Message----- From: ceph-devel-owner@xxxxxxxxxxxxxxx [mailto:ceph-devel-owner@xxxxxxxxxxxxxxx] On Behalf Of Sage Weil Sent: Friday, September 26, 2014 2:27 AM To: ceph-devel@xxxxxxxxxxxxxxx Cc: Somnath.Roy@xxxxxxxxxxx; Allen.Samuels@xxxxxxxxxxx; dieter.kasper@xxxxxxxxxxxxxx; PVonStamwitz@xxxxxxxxxxxxxx; Shu, Xinxin; haomaiwang@xxxxxxxxx; s.priebe@xxxxxxxxxxxx; Chen, Xiaoxi; milosz@xxxxxxxxx; Wang, Zhiqiang; Ma, Jianpeng; gdror@xxxxxxxxxxxx; vuhuong@xxxxxxxxxxxx; mark.nelson@xxxxxxxxxxx Subject: Weekly performance meeting Hi everyone, A number of people have approached me about how to get more involved with the current work on improving performance and how to better coordinate with other interested parties. A few meetings have taken place offline with good results but only a few interested parties were involved. Ideally, we'd like to move as much of this dicussion into the public forums: ceph-devel@xxxxxxxxxxxxxxx and #ceph-devel. That isn't always sufficient, however. I'd like to also set up a regular weekly meeting using google hangouts or bluejeans so that all interested parties can share progress. There are a lot of things we can do during the Hammer cycle to improve things but it will require some coordination of effort. Among other things, we can discuss: - observed performance limitations - high level strategies for addressing them - proposed patch sets and their performance impact - anything else that will move us forward One challenge is timezones: there are developers in the US, China, Europe, and Israel who may want to join. As a starting point, how about next Wednesday, 15:00 UTC? If I didn't do my tz math wrong, that's 8:00 (PDT, California) 15:00 (UTC) 18:00 (IDT, Israel) 23:00 (CST, China) That is surely not the ideal time for everyone but it can hopefully be a starting point. I've also created an etherpad for collecting discussion/agenda items at http://pad.ceph.com/p/performance_weekly Is there interest here? Please let everyone know if you are actively working in this area and/or would like to join, and update the pad above with the topics you would like to discuss.
