synchrone/asynchrone

 FILESYSTEMIO_OPTIONS option is currently set to the value "none", indicating a call mode functions SYNCHRONOUS Linux system (the file system) and then a delegation of management to Linux I / O. And therefore, no ASYNCHRONOUS mode (which would hand the client applications of the base, while the writing may not be performed on disk but in the Linux buffer), and no DIRECT-IO ( no delegation to Linux because bypass system functions of Linux, and thus buffers Linux, and will directly write to the clusters of file system).
When database is setup with the Synchrone mode and the os linux is setup with Asynchrone mode, What is the behavior of the base? (synchrone/asynchrone/performances) ?

Howdy, Stranger!
