And now I want to figure out which is the best blocksize, relative to the kernel, I should read from the socket. Is it easier for the kernel, when I read 4k blocks from the networkbuffer or doesn't matter? I want to write the serverprogramm in relative to have the best performance, so I think that is fundamental to know something about the internel copy prozessing of the kernel. -- Regards Neal P.S.
