Then why so many lost?

Look at your queryperf data file and figure out what is not hosted by 
you.  Some of my systems get around 60,000 QPS with none lost.  If 
really do host these on same system, and are really lost, then will need 
other research.

Even if you are doing recursive work, your results are quite slow. you 
may want to look in your queryperf input to see what is causing 
problems. (It may not be a realistic, real world input set.)
