How to parse the names of all users in vk?

Question

In contact with

How can you parse the names of all users in vk in an acceptable time?
Now I'm doing parsing with selenium and it's not very fast.
1.How can I prevent the entire page from loading, and only load the necessary information (which should reduce traffic and speed up loading).
2.How much will rewriting requests in several threads help, are there any restrictions on the server side?
3. How realistic is it to keep the information up to date, i.e. what will be the delay between two complete passes over all id? And how to determine the last id?

Answer 1

Write a parser in any PL that you know, using the VK api, sorting through the id, take the names.
Or look for someone who can sell the database with the data you need, VK (and not only him) is already parsed up and down. I can arrange the latter.
