Efficiency Comparison of Blocking and Non-blocking TCP/IP Sockets using Java in Single and Multi-core Systems

摘要

Blocking sockets had been the default method of TCP/IP communications in Java before the non-blocking sockets were introduced in Java 1.4. Although programmers can now use any of these sockets, they may have doubts about what kind is more efficient This issue becomes especially complicated if they use sockets in multi-core systems which have lately started to be commonly used. This paper is aimed to test both kinds of sockets in Java and compare their efficiency in single and multi-core systems. We run experiments and conclude how to get the best performance form client server applications for varying numbers of clients and application buffer sizes using both types of sockets in 1,2, and 4-core architectures.
