Can be ``posix``, ``dpdk`` - or ``rdma``. Posix uses standard TCP/IP networking and is default. - Other transports may be experimental and support may be limited. -:Type: String -:Required: No -:Default: ``posix`` - - -``ms async op threads`` - -:Description: Initial number of worker threads used by each Async Messenger instance. - Should be at least equal to highest number of replicas, but you can - decrease it if you are low on CPU core count and/or you host a lot of - OSDs on single server. -:Type: 64-bit Unsigned Integer -:Required: No -:Default: ``3`` - - -``ms async max op threads`` - -:Description: Maximum number of worker threads used by each Async Messenger instance. - Set to lower values when your machine has limited CPU count, and increase - when your CPUs are underutilized (i. e. one or more of CPUs are - constantly on 100% load during I/O operations). -:Type: 64-bit Unsigned Integer -:Required: No -:Default: ``5`` - - -``ms async set affinity`` - -:Description: Set to true to bind Async Messenger workers to particular CPU cores. -:Type: Boolean -:Required: No -:Default: ``true`` - - -``ms async affinity cores`` - -:Description: When ``ms async set affinity`` is true, this string specifies how Async - Messenger workers are bound to CPU cores. For example, "0,2" will bind - workers #1 and #2 to CPU cores #0 and #2, respectively. - NOTE: when manually setting affinity, make sure to not assign workers to - processors that are virtual CPUs created as an effect of Hyperthreading - or similar technology, because they are slower than regular CPU cores. -:Type: String -:Required: No -:Default: ``(empty)`` - - -``ms async send inline`` - -:Description: Send messages directly from the thread that generated them instead of - queuing and sending from Async Messenger thread. This option is known - to decrease performance on systems with a lot of CPU cores, so it's - disabled by default. -:Type: Boolean -:Required: No -:Default: ``false`` - - |
