What happen in your shell?
Do you have the index?
can you try
>> USING PERIODIC COMMIT 10000
>> LOAD CSV WITH HEADERS FROM "file:C:/test/tls206_part01.txt" AS csvLine
WITH csvLine LIMIT 10
>> CREATE (p:Person { person_id: toInt(csvLine.person_id), doc_std_name_id:
>> csvLine.doc_std_name_id , person_name: csvLine.person_name });
