Performance considerations in Proxy based nework applications

Many details on performance considerations on proxy based networking applications are given here. 


There are some more performance considerations in developing proxy based applications. Here they are:

• Use Hugelbfs system to for running code and for application context memory (for connections):  Please see this for getting understanding of this technique.
• Use User space RCU wherever possible:  See the RCU related information here.
• Use Futexes as part of RCU implementation for add/delete operations.  See about Futexes here. 
• Use posix spinlock kind of Mutexes only for small portion of the code.
• Use UIO based Interrupt indication to the User space processes while dealing with memory mapped hardware accelerators.
