Q: 

How to determine a good value for -load-average using gnu Make ?

In Make this flag exists:

-l [load], --load-average[=load] Specifies that no new jobs (commands) should be started if there are others jobs running and the load average is at least load (a floating-point number). With no argument, removes a previous load limit.

Do you have a good strategy for what value to use for the load limit ? It seems to differ a lot between my machines.

A: 

Acceptable load depends on the number of CPU cores. If there is one core, than load average more than 1 is overload. If there are four cores, than load average of more than four is overload.

People often just specify the number of cores using -j switch.
