Sun has enhanced the TCP/IP stack in the Solaris 10 Operating System to deliver very high performance for single-CPU systems while simultaneously improving scalability across multiple CPUs. The synchronization and cross-communication overhead between CPUs (necessary when scaling across a very large number of CPUs) is reduced by vertically partitioning the workload using an IP classifier-based lockless design. The Solaris 10 TCP/IP stack is also designed to seamlessly accommodate future technologies such as offload, 10 Gigabit Ethernet, Remote Direct Memory Access (RDMA), and others into Solaris.
