With a single file descriptor, Is there any performance difference between select, poll and epoll and …?

Question

The title really says it all.

The and ... means also include pselect and ppoll..

The server project I\'m working on basically structured with multiple threads.

According to the link: http://www.intelliproject.net/articles/showArticle/index/io_multiplexing.

If you use only one descriptor:

• select: 201 micro seconds.
• poll: 159 micro seconds.
• epoll: 176 micro seconds.

Seems poll will be a better solution in such situation.
