The following options are supported:
Specifies the number of concurrent slow filters that may be run on a print server. A default value of 1 is used if none is specified. Depending on server configuration, a value of 1 may cause printers to remain idle while there are jobs queued to them.
Specifies the number of concurrent notification processes that can run on a print server. A default value of 1 is used when none is specified.
Specifies the file descriptor resource limit for the lpsched process. A default value of 4096 is used if none is specified. On extremely large and active print servers, it may be necessary to increase this value.
Specifies the number of file descriptors that the scheduler reserves for internal communications under heavy load. A default value of 2 is used when none is specified. It should not be necessary to modify this value unless instructed to do so when troubleshooting problems under high load.
