 * The recommended buffer size is n*TCPBUFFLEN - 4 bytes.
 * To get your buffer size, do: dsmc query options|grep TCPBUF
 * 32kB seems to be the new default, 31kB was the old.
 *
 * An additional factor is the pipe buffer size. Since we don't do threading
 * (yet), we hide a little bit of latency if we don't read more than the pipe
 * buffer can hold at a time. On Linux 2.6 this is 64kB.
 *
 * So, I would recommend a BUFLEN of 64kB if your TCPBUFLEN is above the
 * 64kB + 4 bytes limit or if your TCPBUFLEN is lower, the 
 * n*TCPBUFFLEN - 4 bytes that gets you closest to 64kB.
 *
 * For a default tuned TSM client on Linux, BUFLEN should thus be 32*1024*2-4.
