Transaction submission improvement numbers?

[algotradingstrategies]

Hi,

I came across your medium articles and youtube videos about running your own polygon node for a flashbot arbitrage trader (e.g. https://medium.com/coinmonks/pros-and-cons-of-running-a-polygon-node-as-an-arbitrage-trader-743822112fb). Great work!

I was wondering whether you also have some performance improvement numbers with regard to transaction submission, in addition to the response time improvements yiu reported here?

That is, is it faster to get a transaction into the blockchain via your own node compared to e.g. Alchemy?

I am using an API service like Alchemy (Quicknode, actually), and what I am experiencing is the following: Say I see an opportunity in block number 35677000, and submit my transaction to trade it, my transaction (having set the gasprice high enough) is included in the blockchain earliest in block 35677002, more often actually in block 35677003 (which is mostly too late). I also looked at the data in the mempool explorer of e.g. blocknative, they provide a field "pending timestamp" (presumably the time when my transaction was received by the nodes (?)). What I see there in terms of time (ms) is that from the time I submit my transaction until this "pending timestamp" there is a time detla of typically between 400ms and 1000ms (sometimes up to 2000ms). So I am wondering if you have any data comparison for transaction speed along these lines between using private polygon node and API service, from your experience?

Thanks!!!

Oh actually I haven't checked those. I might add them once I do.
