Performance Improvements, pt. II

[arboleya]

Building upon part one (#3576) of this series, and while we strive for faster transaction processing time, we should now dissect everything from start to end regarding all network requests necessary for the entire transaction flow and cycle—but now from a browser perspective.

Unlike in part one, this chapter must go beyond the submission and analyze everything that happens until the end, including transaction settlement and (optional) retrieval. It should not be limited to the SDK but include everything from a connectors/wallet perspective, which will inevitably shift the focus to front-end applications.

We should be creative and consider optimistic techniques and whatever else we can.

The end goal is to make tx's super snappy.
