What is the hardware ? How many domains ? Where is postfix ultimately
delivering to ? Is this the MX machine? Are you also running spam
checks ? 

In general the best idea is have multiple boxes behind load balancers so
that you can attain high availablity and load balancing 
You should also do 

1) Maintain complete userlist on the same machine , so that Postfix can
quickly reject messages for wrong recipients

2) Get datafeed from rbls like spamhaus atleast and reject spams
outright using a local dns server

3) Use a caching nameserver and reject mails from domains that dont
resolve

4) Have a different machine without amavis to do delivery , incase mail
delivery  is to the internet
