The perfdump Utility
Tuning
There are two ways to tune the thread limit: through editing the
magnus.conf
file and through the Server Manager.
If you edit the
magnus.conf
file,
RqThrottleMinPerSocket
is the
minimum value and
RqThrottle
is the maximum value.
The minimum limit is a goal for how many threads the server attempts to keep
in the
WaitingThreads
state. This number is just a goal. The number of
actual threads in this state may go slightly above or below this value. The
default value is 48. The maximum threads represents a hard limit for the
maximum number of active threads that can run simultaneously, which can
become a bottleneck for performance. The default value is 512.
If you use the Server Manager, follow these steps:
1.
Go to the Preferences tab.
2.
Click the Performance Tuning link.
3.
Enter the desired value in the Maximum simultaneous requests field.
For additional information, see the online help for the Performace Tuning page.
The perfdump Utility
The
perfdump
utility is a service function built into Enterprise Server. It
collects various pieces of performance data from the web server internal
statistics and displays them in ASCII text.
To install
perfdump
, you need to make the following modifications in
obj.conf
in the
netscape/server4/https- server_name /config
directory:
1.
Add the following object to your
obj.conf
file (after the default object):
<Object>
ppath="/usr/netscape/server4/docs/.perf"
Service fn="service-dump"
</Object>
