The document discusses optimizing a mobile site for India. It notes that over 50% of India's 400 million internet users will only access the internet via mobile. The site mobshare.in created a stripped-down mobile site at m.mobshare.in to optimize for mobile use by reducing image/CSS file sizes and domain requests. It also recommends techniques like using direct IP addresses instead of domain names to improve performance on mobile networks. The goal was to create a lightweight site that focused content and could be optimized for different mobile models common in India.

mobile site

17. Optimization tricks

18. Why?
33% mobile penetration
in India by 2011

19. 400 million people,
25-50 million with
Internet on the mobile.

20. Over 50% of them would
only use
Internet on the mobile.

21. We made our site using
stuff we were familiar
with. PHP, Symfony,

22. and in
2 weeks.

23. Optimization: Images

mobshare.in Interative,
Large
banner 100KB

banner <1 KB Tiny

26. Bandwidth is expensive
10paisa/10KB

27. Optimization: CSS

28. CSS size of mobshare.in
> 85KB

29. CSS size of m.mobshare
< 3KB, all inline

30. Optimization: Requests

31. As fewer domain names
as possible

32. Mobshare.in
8-12 domains,
*.cdn.mobshare.in

33. m.mobshare.in
1 domain, 1 direct IP

34. Direct IP?
DNS resolution on a
mobile is really expensive

35. http://67.207.130.241/
index.php?asset

36. Our Open Source tool:
nginx-asset-hot-cache:
http://github.com/mobme/ngnix-asset-hot-cache/
