@@ -651,6 +651,19 @@ ionice_priority None I/O scheduling priority of
priority of the process. Work only with
ionice_class.
Ignored if IOPRIO_CLASS_IDLE is set.
eventlet_tpool_num_threads auto The number of threads in eventlet's thread pool.
Most IO will occur in the object server's main
thread, but certain "heavy" IO operations will
occur in separate IO threads, managed by
eventlet.
The default value is auto, whose actual value
is dependant on the servers_per_port value.
If servers_per_port is zero then it uses
eventlet's default (currently 20 threads).
If the servers_per_port is nonzero then it'll
only use 1 thread per process.
This value can be overridden with an integer
value.
