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.
