Compiler
GNU Make -j [jobs], --jobs[=jobs]
Specifies the number of jobs (commands) to run simultaneously. If there is more than one -j option, the last one is effective. If the -j option is given without an argument, make will not limit the number of jobs that can run simultaneously.

machines with multiple processors can attach network programs of higher priorities to a processor that is little consumed or idle.
