Uncovering a job

Recently, HeadSpin ’ s Digital Experience AI Platform detected various critical execution topic occurring with a global consumer subscription app in Singapore. We presented them with the following info collected from real devices running their app on existent networks in Singapore.

Images be performing very poorly

Images were lade so slowly that they were crippling performance and menace user engagement. The app was conduct 36.089 seconds just to download images.

CDN and API link were debatable

Both API and CDN performance were crippling app performance.

Some SDKs be slow

HeadSpin showed engineers that many 3rd Party SDKs be connecting slowly for user in Singapore.

Root Cause of These Issues

When we looked more close at how the app was handling asking, we found that that API and CDN IPs were mapping to servers in North America instead of to local host near Singapore.

Requests grow from Singapore and mapping to servers in North America be result in eminent hop times, high TTFB and poor user experience.

Adding Value

Based on insights provided by HeadSpin, engineers were able to quickly and seamlessly displace to a CDN with lower latency and fix debatable API connectedness. App execution in Singapore returned to normal, bringing value to the company in a smorgasbord of fashion:

Identifying unnamed issues

HeadSpin proactively expose previously unknown/unidentified performance issues. Without HeadSpin, these issues would have likely gone unobserved and unfixed, negatively impacting conversion rate and revenues in Singapore.

Understanding local problems — remotely

With HeadSpin, the company was able to trace and fix a very local trouble — in a location where they didn ’ t have an technology presence or resourcefulness — all from the comfort of web browser in California. With HeadSpin technologist remotely accessed device in Singapore and debug real-world performance issue without having to rent local resources. Rather, they could have the app the way that real users in Singapore did.

Arriving at a answer — expeditiously

HeadSpin ’ s assist technologist efficiently understand the beginning cause of issues. Enacting a solution took second, not weeks — helping developers continue productive. They didn ’ t hold to research for a needle in a haystack to understand what was occur.
