Sample benchmark code for comparing IO multiplexing methods

Usage

Server:

Usage: ./udp_msg_server [ OPTIONS ]
Options:
[-p, --port LISTEN_PORT]
[-S, --scheduler] Scheduler Algorithm (OTHER, BATCH, IDLE, FIFO, RR)
[-P, --priority NUMBER] Realtime priority between 0.99 for realtime schedulers
[-r, --receive-buffer-size SIZE]
[-m, --method SELECT|EPOLL|THREAD]

Scheduler Types can be: OTHER (default), BATCH, IDLE, FIFO, RR

Client:

Usage: ./udp_msg_client [ OPTIONS ]
Options:
[-s, --server SERVER_IP] Remote Server Ip
[-p, --port PORT] Remote Server Port
[-m, --msg-payload PAYLOAD] Between 0..1500
[-t, --total TOTAL_SEND] Number of packets
[-S, --scheduler] Scheduler Algorithm (OTHER, BATCH, IDLE, FIFO, RR)
[-P, --priority NUMBER] Realtime priority between 0.99 for realtime schedulers
[-c] Use connected udp mode
[-h, --help]

Benchmark - 1

Server:

• Ethernet: Broadcom Corporation NetXtreme BCM57766 Gigabit Ethernet PCIe
• CPU: Intel i5-3330S CPU @ 2.70GHz Quad Core

Client:

• Ethernet: Broadcom Corporation NetXtreme BCM5721 Gigabit Ethernet PCI Express
• CPU: Intel Xeon CPU 3040 @ 1.86GHz

There are 4 gigabit switch between client and server. 1 million packets sent for each test.
