Network applications can benefit from reduced CPU cycles by amortizing the system call overhead of network I/O operations. In this talk Rahul et al review two existing interfaces for network I/O batching namely recvmmsg()/sendmmsg() and SO_RCVLOWAT and then propose extensions to these mechanisms.

We show an 8x syscall reduction with our traffic patterns (gaming scenarios) with the usage of such extensions.
