I suspect that unless most of the memory used by each "mode" of the 
net fits in the cache, the difference won't be all that big, since 
every block cycle causes massive amounts of cache misses anyway. 
Also, as soon as you have hand disk recording going on, you'll have a 
butler thread throwing RT data out of the cache all the time. (Same 
effect that has surprized some RTL and/or RTAI users by causing 
*higher* latencies for the RT threads on faster CPUs.)
