Posix AIO can suffer from severe - limitations. For example, on some Linux versions the - real-time signals that it uses are broken under heavy load. - Other systems only allow AIO when special kernel modules are - loaded or only allow a certain system-wide amount of async - requests being scheduled. Systems based on glibc (most Linux - systems) only allow a single outstanding request per file - descriptor which essentially makes Posix AIO useless on systems - using the glibc implementation. - - To work around all these limitations, the aio_pthread module - was written. It uses a pthread pool instead of the - internal Posix AIO interface to allow read and write calls - to be process asynchronously. A pthread pool is created - which expands dynamically by creating new threads as work is - given to it to a maximum of 100 threads per smbd process. - To change this limit see the "aio num threads" parameter - below. New threads are not created if idle threads are - available when a new read or write request is received, - the new work is given to an existing idle thread. Threads - terminate themselves if idle for one second. - - - - Note that the smb.conf parameters aio read size - and aio write size must also be set appropriately - for this module to be active. - - - This module MUST be listed last in any module stack as - the Samba VFS pread/pwrite interface is not thread-safe.
