Piwik now works on websites with 100M pageviews per month and more (much more) with the right setup

How it handles that traffic? It would be great if they could share the architecture because using Mysql for analytics is not easy, you can't expect Mysql to handle concurrent queries that needs to aggregate billions of records when I visit the dashboard.

So to answer the original question: Nope, doesn't work.

(Quick test: if you're counting page views in millions per day, you're gonna have a tough time).

Piwik does scale to millions of pages per month. We've managed installs of Piwik at _1 billion_ pages per month that's 30 million per day! Don't believe what you read on Hacker News ;-)
