Hi all, Recently there was chat about how PERFORMANCE_SCHEMA was enabled by mistake and it should be disabled in the 10.0 series. I'm curious - how many of you are using PERFORMANCE_SCHEMA? Is it a problem to turn it on, if you use it? I'm referring to: https://mariadb.atlassian.net/browse/MDEV-6249 Looking from the webscalesql list, there are examples of performance degradation: https://groups.google.com/d/msg/webscalesql/B-4bPIb8mHI/eUNsl0lSfbMJ https://groups.google.com/d/msg/webscalesql/B-4bPIb8mHI/-YZMMCuPw3QJ quote: "Our perf testing agrees with your assessment (we see about a 5%-6% perf hit when it's included and on, and a 2%-3% hit when it's included but off)" Please discuss this, either here or on MDEV-6249 Thanks cheers, -colin -- Colin Charles, Chief Evangelist, SkySQL - The MariaDB Company blog: http://bytebot.net/blog/| t: +6-012-204-3201 | Skype: colincharles
