Inserting dummy 200000 data using Faker

Browser could render 80,000 data but failed while trying to render 1 lakh.
2lakhs data could be inserted in MySQL under 20 secs with chunking.
3lakhs data insertion failed (Exception: Allowed memory size of 134217728 bytes exhausted (tried to allocate 16777224 bytes))
