UsingMonitoring Data to Tune YourServerThissection describes the performance information available through the Admin Console,
perfdump,the command-line interface, and stats-xml. It discusses how to analyze that
informationand tune some parameters to improve your server’s performance.
Thedefault tuning parameters are appropriate for all sites except those with very high volume.
Theonly settings that large sites might regularly need to change are the thread pool and keep
alivesettings. Tune these settings at the conguration level in the Admin Console or using wadm
commands.It is also possible to tune the server by editing the elements directly in the
server.xmlle, but editing the server.xml le directly can lead to complications.
perfdumpmonitors statistics in the following categories, which are described in the following
sections.In most cases these statistics are also displayed in the Admin Console, command-line
interface,and stats-xml output. The following sections contain tuning information for all
thesecategories, regardless of what method you are using to monitor the data:
■“ConnectionQueue Information” on page 49
■“HTTPListener (Listen Socket) Information” on page 51
■“Keep-AliveInformation” on page 53
■“SessionCreation (Thread) Information” on page 57
■“FileCache Information (Static Content)” on page 59
■“ThreadPool Information” on page 65
■“DNSCache Information” on page 68
Inaddition, the statistics information displayed through the Admin Console, the
command-lineinterface, and stats-xml contains other categories not contained in the
perfdumpoutput. Tuning these statistics is discussed in the following sections:
