About Server Performance
Web servers have become increasingly important for both internal and external
business communications. As Web servers become more and more business-
critical, server performance takes on added significance. Netscape’s Enterprise
Server continues to lead in this area, by setting a new standard for performance.
Netscape Enterprise Server 4.0 was designed to meet the needs of the most
demanding, high traffic sites in the world. It flexibly runs on both Unix and
Windows NT and can serve both static and dynamically generated content.
Enterprise Server can also run in SSL mode, enabling the secure transfer of
information.
Because Netscape Enterprise Server is such a flexible tool for publishing,
customer needs vary significantly. This document guides you through the
process of defining your server workload and sizing a system to meet your
performance needs. This document addresses miscellaneous configuration and
Unix platform-specific issues, CGI-related performance tuning problems, and
other common situations. It also describes the
perfdump
performance utility
and tuning parameters that are built into the Netscape Enterprise Server 4.0.
The document concludes with a discussion of the two web server
benchmarking packages: SpecWeb and Webstone.
Performance Issues
The first step toward sizing your Enterprise 4.0 server is to determine your
requirements. Performance means different things to users and to webmasters.
Users want fast response times (typically less than 100 ms), high availability (no
“connection refused” messages), and as much interface control as possible.
Webmasters and system administrators, on the other hand, want to see high
connection rates, high data throughput, and uptime approaching 100%. You
need to define what performance means for your particular situation.
Here are some areas to consider:
• Peak concurrent users
• Security requirements
