by reading the lwn article it seems postgresql is hit especially hard per its design and "heavy" use of fsync, I have yet to find similar impact on mysql.

- olavgg 9y agoAll SQL databases are "heavy" users of fsync. Though, this problem is not relevant on FreeBSD nor Illumos. Error handling for a operating system is really complex stuff. I'm surprised that this isn't working properly, fsync is not about speed, but reliability. Userland applications expect it to work and behave as intended.
