Global synchronization is IMHO much less important at the second by second 
level. In any case we run synchronisation within 2 seconds across the Atlantic 
so its really not that big a deal.

Analysis of results on a single server at the second by second level would be 
very interesting and worthwhile IMHO. Knowing that one got 20 requests a second 
for 15 seconds is quite interesting. Knowing that one got 300 in a minute less 
so.

When we tunned the CERN server we looked at the number of connections per second 
that it peaked at then looked at the bottlenecks.
