We'd be working with them entirely via API code—it's just a bridge app between two systems—or using the Control Panel for troubleshooting. Everything else would be aggregate numbers, as it's intended to be an automated system.

Answers.Text: Populating 1000 entries won't be a problem, so you won't run into critical issues (unless you want to store - let's say - 100 redactor fields in each entry). If you are able to batch your inserts to a smaller amount than 1000 it will be fine as well. Otherwise I would highly suggest you to store your new entries as simple rows/records in a custom table and include them in Crafts ecosystem via cronjob. Creating a new Entry/Element means to create a record in at least 4 different tables - if you have a matrix field even more. So you'll reach 6000 queries while storing 1000 entries easily

  It depends more on how you are going to create and display them. I had to import 20k elements this weekend and I had to be careful to store them step by step.
  
  Depending on your server/hardware - you can't just insert 10k elements in one request. There is a function `App::maxPowerCaptain()` to disable the timeout but I still faced overflow errors.
  
  And of course you can't display so many users in one single page without using a pagination or Ajax
  
  Besides that - Craft is able to handle such an amount of elements if you can do it in your code as well
