Exploring the Performance of Select-based Internet Servers

Internet servers, Web servers, performance, select, event dispatching Several previous studies have examined techniques for improving Internet server performance by investigating and improving operating system support for event-dispatching mechanisms. These studies have been mainly motivated by the commonly held belief that the overhead incurred in obtaining network I/O events using the select system call was too high to be used in environments with high request loads and large numbers of concurrent connections. However, recent work by Chandra and Mosberger [6] shows that a properly implemented selectbased server can outperform servers that utilize new and improved event-dispatching mechanisms that are significantly more scalable than select.
