That's nearly 3,000 addresses per subnet, is that required ?

I believe that reducing the number of available addresses can make a 
significant impact on startup times - so if you only needed (say) 300 
addresses, cutting each subnet down to whatever is needed plus a 
reasonable margin should deal with the problem.
