Default: 0
Range: 0, 2 – 64
Related parameters: n_update_threads

Use this parameter to configure the number of RPC buffers to be used by the Client. If you let this parameter default or set it to 0, the client uses 4 times n_update_threads RPC buffers or 2 buffers when n_update_threads is 0. When you have DMSII links enabled, this parameter is set to the number of extract workers unless the default value is larger. Raising this value might improve performance by ensuring that there are enough buffers queued to keep the update workers busy at all times.
