Some data is not suited to go through asynchronous streams with a lot of parsing. At some point I needed to pass real-time eeg data to an application and we were exploring Cordova as an option. The jitter and absurd latency (over 15ms) was a non-starter. Things might have gone better but not everything can be solved by immutable data structures.

For comparison, the same data transfer using Electron native plugin took well under 1ms.
