Miscellaneous magnus.conf Directives
MaxProcs
( Unix )
Use this directive to set your Unix server in multi-process mode, which allows
for higher scalability on multi-processor machines. If, for example, you are
running on a four-processor CPU, setting
MaxProcs
to
4
improves
performance: one process per processor.
If you are running Enterprise Server 4.0 in multi-process mode, you cannot run
LiveWire, Web Publisher, and WAI.
This directive results in one primordial process and four active processes:
MaxProcs 4
Note
This value is not tunable from the server.
Accept Thread Information
MinAcceptThreadsPerSocket
/
MaxAcceptThreadsPerSocket
Use this directive to specify how many threads you want in accept mode on a
listen socket at any time. It’s a good practice to set this to equal the number of
processes. You can set this to twice (
2x
) the number of processes, but setting it
to a number that is too great (such as ten (
10x
) or fifty (50x)) allows too many
threads to be created and slows the server down.
CGIStub Processes (Unix)
You can adjust the
CGIStub
parameters on Unix systems. In Enterprise Server
4.0, the CGI engine creates
CGIStub
processes as needed to handle CGI
processes. On systems that serve a large load and rely heavily on CGI-
generated content, it is possible for the
CGIStub
processes spawned to
consume all system resources. If this is happening on your server, the
CGIStub
processes can be tuned to restrict how many new
CGIStub
processes can be spawned, their timeout value, and the minimum number of
CGIStub
processes that will be running at any given moment.
