Hi Dejan, yep ! the modification is efficient now with lrmdadmin, I've tested with following values : lrmadmin -p max-children 24 and the 24 dummy resources are started in quite one shot and also the 24 op monitor are executed in one shot. lrmadmin -p max-children 2 and the 24 dummy resources are started by successive pairs, and same thing for op monitor. So that is really efficient.
Is this value taken in account for any action in Pacemaker ? meaning : configure, delete, start, stop, etc. ?

No, it doesn't. lrmadmin has to be used to set the parameter: lrmadmin -p max-children $LRMD_MAX_CHILDREN Thanks, Dejan P.S.
