Case Study: Mercado Libre cut response time to under 50ms per request with New Relic
Key results
The challenge
As one of Latin America's largest e-commerce and fintech platforms, Mercado Libre faced growing issues with scalability, performance, and downtime. Teams lacked clear insight into error rates and the experience customers were having in the browser, and problems often went unnoticed until after deployment.
The solution
Development teams across Mercado Libre adopted New Relic, including application performance monitoring, browser monitoring, and dashboards. The MercadoPago team rolled it out first, giving engineers the ability to query across applications, surface JavaScript errors, and detect problems before they reached customers.
“Using New Relic, we reduced the error rate down to zero and improved the response time to less than 50 milliseconds per request.”

The results, in context
Using New Relic, Mercado Libre reduced the error rate to zero and improved response time to less than 50 milliseconds per request. The company also reduced the number of virtual machines it used by 20% and reported increased conversion rates from improving the browser user experience.
