SUGGESTION: Deafult MariaDB Server Configuration Variables -

Dear MariaDB Developers,

I am writing to suggest that MariaDB changes its default innodb_read[write]_io_threads default value in order to obtain a better default performance out-of-the-box.

Nowadays, many computers use SSD, or high-speed HDD, so default value, 4, is certainly low.
It should be, in my opinion:

• innodb_read_io_threads = 8
• innodb_write_io_threads = 8

And in the Windows / Linux MariaDB installer, just as innodb_buffer_pool_size is configured depending on the Server, this values shall be increased to:

• innodb_read_io_threads = 16
• innodb_write_io_threads = 16

This is of special importance, as MariaDB uses from 10.2 engine InnoDB, and not XtraDB, and this is the bottleneck which prevents InnoDB having the same performance than XtraDB.

Thank you,
Juan
