For details, see note in changelog which includes links to the original Github PR.

There's no docs on the MariaDB website, but MySQL has a few. Anyway, might be worth including in your custom my.cnf files.

I suspect for most centminmod users who are hosting forums/blogs keeping the pct at 50% or great is probably most convenient--the buffer pools generally aren't larger than 1-2 gb. I know @Xon has mentioned he's running a 1GB buffer pool and he's managing one of the largest forums around.

 

I'd stay with 100% myself, and probably make it explicit as MySQL changed their default to 25% in 5.7.7 when they switched to enabling dump/load on shutdown by default.

I looked, but couldn't find anything in the MariaDB docs about what the default setting for this is.

If you're okay with it, let me know and I'll submit a PR on github centminmod repo explicitly setting this to 100%
