Disk I/O |
To use asynchronous disk I/O, enable it on both SAP ASE and your operating system. See your operating system documentation for information on enabling asynchronous I/O at the operating system level.
Disk I/O always runs faster asynchronously than synchronously. This is because when SAP ASE issues an asynchronous I/O, it does not have to wait for a response before issuing further I/Os.
