A Tokopedia Mobile Web Performance Case Study | by Aatif Bandey | Tokopedia Engineering | Medium
Article Summary
Tokopedia's mobile web was scoring 67-71 on PageSpeed during their biggest sale event. With most traffic on 3G, that meant 5-6 second load times when milliseconds matter most.
Tokopedia, one of Indonesia's largest e-commerce platforms, needed to optimize their Discovery pages (think Black Friday landing pages) for their annual Ramadan sale event. Their engineering team set an ambitious target: boost performance scores from the high 60s to 80+.
Key Takeaways
- Started with PageSpeed scores of 67-71, targeting 80+ for sale events
- Most users on low-end phones with 3G connections during peak traffic
- Discovery pages are highly dynamic with different layouts per sale
- Tech stack: React, Apollo Client for state, and Emotion for CSS
Critical Insight
The team tackled legacy code and performance bottlenecks to dramatically improve load times for millions of users on constrained devices and networks.
