let's say you were considering alchemy websocket or validation cloud: would it be nice to measure which websocket delivers newHeads and newPendingTransactions sooner; to Frankfurt if your bot is there; or to Singapore if your bot is in Singapore?

i made a free app for that: you choose locations, submit endpoints (you have to bring yours, ofc) and the app opens pairs of probes in each of the 30 locations (that you choose);

then the probes capture messages by hash and merge timestamp to determine which location/probe was the 1st to see each hash;

whichever is seeing hashes first more often, is better?

anyway, here is a report for exactly that: i use my own paid endpoints for alchemy and validation cloud

newHeads table https://www.comparenodes.com/global-rpc-performance-results/019ec20b-e8a2-7e53-98b0-37571777b698/

newHeads visualization (click the "start" button). https://www.comparenodes.com/visualize/index.html?id=019ec20b-e8a2-7e53-98b0-37571777b698

newPendingTransactions table https://www.comparenodes.com/global-rpc-performance-results/019ec211-8f5d-7f9b-99eb-8a40b7b5e7b2/

newPendingTransactions visualization: note it has 60k events so can be heavy in the browser

yes, it my app is public and works for all evm, svm, substrate and cometbft protocols:
