What characteristics of the server to choose for parsing?

Question

Parsing

Good afternoon, it is planned to rent a server for parsing information from the site.
I do not know what information is needed to determine the best characteristics of the desired server, but on a weak 4-core laptop with a processor frequency of 1.6 Hz, parsing is completed in about 20 minutes.
When parsing, about 900 pages of the site are loaded

Answer 1

As already mentioned above, the problem is not in the processor.
Parsers are slow in nature, while the page loads you have time to parse it, so the processor is not loaded.
Memory can be estimated something like this: 20 - 100MB + page size * 12 ( DOM )
That is, if you do not parse a bunch of pages, but create a pool of workers, then the simplest hosting with 512 brains can handle it.
