The invention discloses a data processing method and device. The method includes the steps that data to be sent issued by an upper layer application are received, and the received data to be sent are cached into a data sending memory pool which is established in advance; if it is determined that a data sending moment arrives according to a set data sending cycle, at least one of the data to be sent cached in the data sending memory pool is written into a data receiving memory pool of a data receiver in an RDMA Write mode. According to the scheme, due to the fact that the RDMA Write mode can be used for writing multiple data cached in the memory pool of a data sender into the memory pool of the data receiver at the same time, the problems that when an RDMA Send mode is used for sending data item by item, the efficiency is low, data can overflow easily and errors can occur easily can be solved, and on the premise that the data sending frequency is reduced substantially and the data overflow probability is lowered, the purpose for improving the data sending efficiency is achieved.
