What is the maximum comments to be handled

I want to know does WordPress is the best CMS for what we want to reach with the max high-performance site?
What is the maximum amount of comments, users, posts WordPress can handle?

WordPress doesn’t place any arbitrary limits on comments, users, posts, or any other content type. It’s whatever your infrastructure can support. WordPress is used on major news websites like TechCrunch, New Yorker, Variety, Quartz, TED, CNN, CBS, NBC, etc. WordPress.com, which runs WordPress under the hood, see over 70 million new posts and 77 million *new* comments *each month.*

I want to believe these examples can fit your definition of a “high-performance site” 😀

But irrespective of the CMS you use, beyond a certain point, it becomes less a function of the capabilities of a particular CMS and hardware, and more a function of the technical expertise you bring to the table… as you’d need a detailed technical analysis of your current performance bottlenecks before you can even make the right decisions… far beyond what random users on a forum can tell you (however knowledgable and well-intentioned they may be).

We are migrating a website to WordPress. It has 10 million comments, 20K users, and 20K articles. When we imported the comments only so the site crashed.

Can you provide some more detail for us? What CMS are you migrating from? How are you doing these imports? What sort of hosting infrastructure do you have, and what limits are configured in your webserver? What exactly does “crashed” mean? What do you see in your server’s logs when the site “crashes”?
