The Ultimate Guide to High Availability with MariaDB

Very High CPU Use on Windows Subsystem For Linux

Hi,

I've been using MariaDB on Ubuntu for some time and not had any significant problems.

But I've got an issue I can't fix here. I'm trying to set up a local development server on my Windows 10 workstation using the Windows Subsytem for Linux. I installed Ubuntu 20.04 along with NGINX, PHP, and MariaDB (10.3). I installed MariaDB out of the Ubuntu repository.

Noticing that MariaDB is using 190-200% of CPU even while just "idling." So far I haven't been able to nail down the problem. I checked the log file and see this:

2020-05-09 11:55:31 0 [ERROR] InnoDB: Linux Native AIO interface is not supported on this platform. Please check your OS documentation and install appropriate binary of InnoDB. 2020-05-09 11:55:31 0 [Warning] InnoDB: Linux Native AIO disabled.

Any ideas what might be going on here? Thanks for the help.
