Timeout for Basic I/O Operations (<timeout> Section)
We do not recommend you changing this section unless absolutely necessary (and you know what you are doing). The section has the following syntax ( purple marks default values that will be used if corresponding parameter is omitted):
< timeout exec="exec( 100)" priority="priority( 10)"/>
Exec parameter specifies a sleep timeout in milliseconds, which is performed after all VSPs has been polled. This value can be decreased if you have many VSPs and experience problems with VSPDL performance. Setting exec to 0 causes your PC to poll the ports at maximum possible speed. This leads to high CPU utilization by the VSPLD but may be necessary if you want to achive best possible performance in a system with a large number of virtual ports.
Priority parameter specifies priority level for the VSPdaemon process.
