Actual Data from a serious test with blocks from 0MB - 10MB

Jonathan Toomim's work on blocksize measurements is not appreciated widely enough.
The data from his intensive global testnet investigations is presented in a nice and informative interactive format here:
Jonathan presented this data at scaling bitcoin Hong Kong, and then proceeded to spend many more days in Asia talking to miners there, the results of which have been summarized in other posts.
The tests charted at the link above involved generating blocks in London, and watching how they propagated across the world.
TL;DR: if you're in China, you have a problem whose name is the Great Firewall, that affects even tiny blocks. Otherwise, your experience is pretty good, even up to 9+MB blocks. Have a look at the data for yourself.
One of the things you'll see Jonathan has been testing is "thin blocks". This is a simple compression technique similar to IBLT or the relay network, but it's built into a fully validating node. It was written by Mike Hearn and is currently available as a patch to XT. It's still being improved but as you'll see from the charts, it can make a huge difference in block propagation times.
In this first test, thin blocks didn't have much effect on larger blocks -- this was due to an index size limit that is now being addressed in both core and XT (technically, "setInventoryKnown" was much too small).
Jonathan is now planning another global test with many improvements to the first. Thank you JT!

Bitcoin is the currency of the Internet. A distributed, worldwide, decentralized digital money. In recent weeks the tensions in the Bitcoin Cash have been escalating rapidly as Bitcoin ABC development team adopted Jonathan Toomim’s ASERT Difficulty Adjustment Algorithm (DAA), and ... Recently, software developer Jonathan Toomim introduced a DAA concept called Aserti3-2d and the specification is available on Gitlab. The BCHN full node team has the code hosted on the “Bitcoin Cash upgrade specifications” page. The controversy really heated up after the Bitcoin ABC development team decided to adopt Jonathan Toomim’s ASERT Difficulty Adjustment Algorithm (DAA), but also included the controversial Infrastructure Funding Proposal (IFP) coinbase rule as well. If the rule was to be applied, approximately 8% of the coinbase reward would be set aside for ... On Sunday, Bitcoin Cash (BCH) developer Jonathan Toomim unveiled a project he’s been working on called Xthinner, a new block propagation protocol that leverages the benefits of lexicographic transaction ordering (LTOR). According to Toomim’s data, Xthinner can compress blocks by 99.6 percent and performs roughly 4x to 6x more efficiently than block propagation concepts like Compact Blocks ...
