Changing this parameter changes the range of priorities used to schedule kernel processes and can have a significant effect on the performance of the system. In general, there is no need to change this parameter unless you add new scheduling classes or reconfigure the priorities of other currently configured classes.
The value of MAXCLSYSPRI must be ``40'' or greater, because the kernel assumes it has at least that great a range of priorities below MAXCLSYSPRI. If you request a MAXCLSYSPRI below ``40'', the system might panic during initialization.
The most important system processes get global priorities at or near MAXCLSYSPRI; the least important system processes get global priorities at or near (MAXCLSYSPRI - 40). The default value of MAXCLSYSPRI is ``99'', which gives all system processes higher priorities than all user processes.
The value of TSMAXUPRI is independent of the configured number of global time-sharing priorities, though we recommend configuring at least 40 time-sharing priorities, as explained in ``Time-Sharing parameter table ts_dptbl''. In the default configuration, there are 60 time-sharing priorities. The system may use the remaining priorities depending on process behavior.
