My experience has been that offload cuts your host TCP cycles by less than 10%, 
while cutting your
throughput in half.  I believe old IBM 3172 performance doc showed that is in 
the ballpark.  BTW: If
you have a CMOS machine, you should look at an 0SA alternative - cheaper yet 
better performance.
