# service is used, otherwise no child will stay alive. This config gives the lower footprint when the

# service is idle. But will use more proc since it has to start a child as soon it's used.

# Set as 'medium', the process manager will be at dynamic. If the service is idle, a number of children

# equal to pm.min_spare_servers will stay alive. So the service can be quick to answer to any request.

# The number of children can grow if needed. The footprint can stay low if the service is idle, but

||||
# not null. The impact on the proc is a little bit less than 'ondemand' as there's always a few
|
||||
# children already available.
|

# Set as 'high', the process manager will be set at 'static'. There will be always as many children as
|
||||
# 'pm.max_children', the footprint is important (but will be set as maximum a quarter of the maximum

# RAM) but the impact on the proc is lower. The service will be quick to answer as there's always many
