The following kernel parameters are used for managing asynchronous
I/O operations. The first four (aio_*)
are related to POSIX asynchronous I/O operations; the last (max_async_ports)
pertains to open ports between processes and the asynchronous disk I/O
driver.
See also “How to Specify Configurable
Parameter Values”.
Asynchronous I/O | aio_listio_max | Maximum number of POSIX asynchronous
I/O operations allowed in a single lio_listio() call. Manpage: aio_listio_max(5). |
Asynchronous I/O | aio_max_ops | System-wide maximum number of POSIX asynchronous I/O
operations allowed at one time. Manpage: aio_max_ops(5). |
Asynchronous I/O | aio_physmem_pct | Maximum percentage of total system memory
that can be locked for use in POSIX asynchronous I/O operations. Manpage: aio_physmem_pct(5). |
Asynchronous I/O | aio_prio_delta_max | Maximum priority offset (slowdown factor)
allowed in a POSIX asynchronous I/O control block (aiocb).
Manpage: aio_prio_delta_max(5). |
Asynchronous I/O | max_async_ports | System-wide maximum number of ports to
the asynchronous disk I/O driver that processes can have open at
any given time. Manpage: max_async_ports(5). |
