Seems to me it would be faster to load the data at the jena interface rather than at the fuseki interface. Since duplicates are ignored you could just open a connection to the model and start adding triples as you read them from the json file.
if you don't want to take your system offline to do this you could do it against a new database and then use mysql replication or export/import to move the data. I don't know if the jena/mysql implementation allows for parallel access to the mysql database without conflicts.
