It seems that the importing process for Scrapebox Page scanner takes way more time than the same importing for harvester (from .txt file). For example, I can import 300k URLs in harvester just in matter of few seconds but the same process for Page scanner takes about half an hour. It's even worse when the URL count is even higher. I tried to import 1M urls and it took like 2-3 hours. Is it because of software architecture, limitation issue or I'm the only one who faces with it?
