Through this page, you can configure some of the technical options of the server which affect its basic operation. These options include:
If you move the server, you should change this location to its new home. Note that changing this variable does not actually move the server. You should shut down the HTTP server and move it by hand after you submit this change. While running, the server should only have restricted access to your system resources. Although you may have to start the server as root, you probably don't want it to be root all the time. The server will automatically change its username to the Unix user you specify here after startup.
Many times, there is already a user named nobody
that is
designed for exactly this purpose. However, on some systems,
nobody
is not a valid user. In that case, you should
create a new Unix user for the server. If you are unfamiliar with creating
Unix users, you should consult your system administrator or your system's
manual.
The server creates a number of processes on your server machine when it
starts up.
The threads of these processes take turns answering requests.
With a threaded server, it makes sense to keep the number of processes
relatively low, and the number of threads high.
The server creates a number of threads on your server machine when it starts
up. These threads take turns answering requests. You can set the number
of threads to achieve a balance between system load and request response
time. The number should be determined by the number of requests you expect
and the speed of the hardware your system runs on. On a low-demand system,
the server may only need five or ten threads. On a very high demand
system, you may want to use as many as thirty threads.
If you are having trouble setting this number, consult your Server Reference Guide for more details. You also have the option of telling the server never to use Domain Name Service (DNS) lookups during normal operation. DNS lookups are a useful tool, however, doing these lookups can be expensive, and you may want to turn them off to get better performance.
NOTE: Be sure you are aware of the consequences of turning off DNS on your server. Remember that hostname restrictions will not work, and hostnames will not appear in your log files.
