How to optimize django-import-export?

Question

I have a data in Excel around 20,000 records. I using django-import-export extension for import data.I tried to import data but very slow about 10 minute. I think one thing to make it slow that is django-import-export render 20,000 records on preview table. I want to know how to speedup?

Answer 1

I made some notes on speeding up django-import-export here . Using the optimisations I describe I could import 20k rows in ~5 seconds on my dev laptop.

The best way is to override save_instance() to use bulk_create() , but there are other optimisations you can make.
