Re: PERFORMANCE_SCHEMA to be disabled in 10.0 (10.0.12)
I personally would prefer if MariaDB had performance schema not
compiled in by default. Then we wouldn't be frustrated every time we
upgrade and find out that the tarball doesn't compile without
performance schema (yes, 10.0.11 doesn't compile).
