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/-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
