Memory Leaks :  Continuous increasing memory consumption growth  with application keeps running called memory leaks.

Sizing of hardware :
 2 transactions  for 1ghz cpu

4 cpu of 3.68ghz


formula = 4*3.68ghz which is 14.72ghz ,so almost one server can run 29 transactions per second .

CPU ,Memory,Disk and Network are mainly areas which we need to focus on for hardware tuning .
