I've had a chance to test these suggestions again on an EC2 i2.4xlarge instance. atime=off made no difference, zfs_prefetch_disable=1 made no difference either.

Running iotop I am not seeing substantial read workloads; it's all writes as expected.

I can't get more than ~65K IOPS.

For lack of something else to try, here are the details of the most recent test I ran:

I set up the test with these commands:

    } catch (Exception e) {
      // Now if authentication fails, when you catch AuthenticationFailedException
      // you have no idea what actually caused the authentication to fail.
      // That will make debugging, especially in the field, very hard
      throw new AuthenticationFailedException();
    }

public class UserManager {
  public void AuthenticatedUser(string userName, string password) {
    if (userName != _userName) {
      //WTF does 'ApplicationException' mean?  It means "something didn't work"
      //That's not very helpful
      throw new ApplicationException("Invalid username");
    }
  }
}
