Disclosed herein are systems, methods, and processes to improve throughput in OpenFabrics and Remote Direct Memory Access (RDMA) computing environments. Data and a header is received. Buffers in which the data and the header are to be written are identified. Placement information for the data and the header is determined based on a size of each buffer, a page-boundary-alignment of the data, and a header alignment of the header. The data and the header are written to the buffer(s) using the placement information. In such computing environments, throughout can be improved by writing data on page boundaries and the header on a header boundary in a second to last buffer.
