I think it is just either issue of memory allocation for transactional data
creation or it could be related to parsing the huge JSON.
Can you try to run the apoc.load.json and just return count(*) without
creating data to see how long that takes?
And then you can combine apoc.periodic.iterate with apoc.load.json to batch
your data creation
call apoc.periodic.iterate("
CALL apoc.load.json('file:///root/output/1532360242087/devices1.json')
YIELD value AS row UNWIND row.devices as val RETURN val
","
MERGE(dev:device{dwwn:val.device_wwn})
ON CREATE SET dev.title='device',dev.sid=val.sid,dev.scsi_3_persistent_res
erve=val.scsi_3_persistent_reserve,
...
", {batchSize:10000, iterateList:true, parallel:false});
you can leave off the "RETURN count(dev)"
and you can also use SET dev += val
to set all properties of the "val" map at once
