> Latency is a cruel mistress. Yes, Bloomberg had fun with latency because of their datacenter locations (about a decade ago they still only had two and a half close to New York). Pages that would paint acceptably in London would be unacceptable in Tokyo as when poorly designed they would require several round trips to render. Once the page rendered there was still the matter of updating the prices, which was handled by separately streaming data from servers close to the markets to the terminals. A very different architecture but rather difficult to test because of the significant terminal-side functionality.
