Have you also considered Percona MySQL server? I think they say they have the best performance (but I haven't tested their implementation yet).

No, unfortunately our company’s and external regulatory compliance policies require us to host all data within the country itself, alongside it being required to be run on an infrastructure that is easily auditable. So as a policy within the company, all our internal services are open source and self hosted.
