We have developed a communications protocol above RPC from SUN. The link is to be used from a large number of different systems, amongst which are PCs. Our problem is that the PC/NFS toolkit from SUN has limited buffersize to 1 kB. This makes throughput efficiency extremely bad. A factor that in our case is critical since we transmit huge amounts of data. I can for instance give an example of transmission of 256 kB. On a UNIX to UNIX link (4k buffers) this transmission takes in the order of 1 to 2 seconds to complete, PC to UNIX is in the order of 8 times slower (we are in this case forced to use 1k buffers) ! Does anybody know of methods to increase throughput in this case, is there other RPC products than SUNs that is more efficient? Has anybody another idea on how to circumvent the problem? Why is SUN making such an unnecessary limitation in PC/NFS toolkit?
