Using less CPU power!

Here they are:

With TSOv4:
TCP STREAM TEST to ... : histogram
Recv   Send    Send                          
Socket Socket  Message  Elapsed              
Size   Size    Size     Time     Throughput  
bytes  bytes   bytes    secs.    10^6bits/sec  

 32768  32768  32768    10.06     713.35   
0.03s user 1.08s system 11% cpu 10.071 total

Without TSOv4:
TCP STREAM TEST to ... : histogram
Recv   Send    Send                          
Socket Socket  Message  Elapsed              
Size   Size    Size     Time     Throughput  
bytes  bytes   bytes    secs.    10^6bits/sec  

 32768  32768  32768    10.06     624.60   
0.01s user 1.24s system 12% cpu 10.061 total
