Please check your location line carefully. If you don't see http://www.sean.de/Solaris/ in your location bar, you might want to check with the original site for the most up to date information.
Important Notice!
SUN managed to publish a Solaris Tunable Parameters Reference Manual, applying to Solaris 8, HW 2/02, and Solaris Tunable Parameters Reference Manual, applying to Solaris 9, HW 9/02. You might want to check there for anything you miss here. Another good read is Solaris Operating Environment Network Settings for Security, if you are concerned about security and denial-of-service attacks.

1. Introduction
Use at your own risk!
If your system behaves erratically after applying some tweaks, please don't blame me. Remember to have a backup handy before starting to tune. Always make backup copies of the files you are changing. I tried carefully to assemble the information you are seeing here, aimed at improved system performance. As usual, there are no guarantees that what worked for me will work for you.

Before you start, you ought to grab a copy of the TCP state transition diagram as specified in RFC 793 on page 23. The drawback is the missing error corre[1] [2] [3] [4] [5] [6] [7] [8] [9] [10] ... 下一页 >>
