Hi phatnth,

It would only depend on your hosting server settings and connection speed between your server and the WordPress CDN. Unfortunately, this is not theme related. Here are the minimum recommended PHP settings for successful import:

   max_execution_time 90
    memory_limit 128M
    post_max_size 32M
    upload_max_filesize 32M

You can check your current server settings under WooCommerce > Status page
