# A lower value for the footprint will allow more children for 'pm.max_children'. And so for
|
|
# 'pm.start_servers', 'pm.min_spare_servers' and 'pm.max_spare_servers' which are defined from the
|
|
# value of 'pm.max_children'
|
|
# NOTE: 'pm.max_children' can't exceed 4 times the number of processor's cores.
|
|
#
|
|
# The usage value will defined the way php will handle the children for the pool.
|
|
# A value set as 'low' will set the process manager to 'ondemand'. Children will start only if the
|
|
# 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
|
|
# children ready to answer.
