Earlier today, I came across this article via Velocity’s always-excellent newsletter. Not just an interesting read in its own right, it’s also incredible validation of the relationship between performance and metrics.
To summarize, this summer marks the start of a massive project to lay the first ever trans-Arctic Ocean submarine fiber optic cables connecting the United Kingdom and Japan. In total, the three cables are expected to cost between $1.8 and $4.5 billion. Why? To reduce latency by a mere 60 milliseconds.
This small latency boost is expected to yield big results:
The massive drop in latency is expected to supercharge algorithmic stock market trading, where a difference of a few milliseconds can gain (or lose) millions of dollars.
These kinds of results are the reason why a similar cable is currently being laid between the UK and the US:
“[The UK-US cable] will cost $300 million and shave “just” six milliseconds off the fastest link currently available.”
At Strangeloop, we’ve recently conducted some research into mobile and desktop latency. I’m working on a post about it, which should be ready next week.
