How to speed up Function in powershell - powershell

Question

I am getting object ids from function. where $objects has 1000 entries. Below is part of main script. Just to get object ids for 1000 OBJECTS running for hours. If $objects count under 10 it runs quick. Is there way I can speed up below function to process 1000 $objects ???
function get_nodes($obj){
if($obj.protectionSource.name -eq $objectName){
$global:_object_id = $obj.protectionSource.id
$global:object = $obj.protectionSource.name
#break
}
if($obj.name -eq $objectName){
$global:_object_id = $obj.id
$global:object = $obj.name
# break
}
if($obj.PSObject.Properties['nodes']){
foreach($node in $obj.nodes){
if($null -eq $global:_object_id){
get_nodes $node
}
}
}
if($obj.PSObject.Properties['applicationNodes']){
foreach($node in $obj.applicationNodes){
if($null -eq $global:_object_id){
get_nodes $node
}
}
}
}
foreach($source in $sources){
if($null -eq $global:_object_id){
get_nodes $source
}
}
return $global:_object_id
}
foreach($object in $objects){ ###2
# get object ID
$objectId = getObjectId $object
}
$sources may have 1000 or more entries. below is one entry. $objects are literally server names ( server1 , server2 etc).
