At the recent NodeDay meetup held at PayPal’s headquarters, several companies shared information about the positive effects Node.js has had on their business. Node.js allows them to run server side JavaScript, which in many cases improves application performance. Examples included the following:
- Groupon’s Node.js deployment handles 50,000 requests per minute with no trouble, and it has improved page load times by 50 percent compared with Ruby on Rails.
- Walmart’s Node.js deployment handled 53 percent of Black Friday sales without a single server going down that day.
- Yahoo’s Node.js deployment responds to 1,680,000-2,000,000 requests per minute.
- PayPal says switching from Java to Node.js improved performance by 35 percent.
