Performance: Network Interface
The PostPath Server™ uses an event-driven mechanism to manage RPC events, an approach that is not constrained by thread performance.
It also uses a high performance networking mechanism, newly available in the Linux 2.6.x kernel (the same kernel used in RedHat Enterprise Linux 4.x), namely the ePoll mechanism. Furthermore, it uses ePoll in edge-triggered mode, maximizing the number of reads and writes that can be carried out per notification and hence also minimizing the number of network notifications required.
Additionally, the PostPath Server™ uses "connection pooling" where applicable - connections to other servers, especially to Active Directory Domain Controllers, are re-used whenever possible to avoid closing and re-opening of connections.
