Cannot consume all pending transactions

Question

I am trying monitoring pending transactions using my local node. I mentioned that my app does not consume all pending transactions. I compared transaction from my app with etherscan.com or dextools.io. Most amount of transactions were not consumed by my app. I am using web3js lib with subscription on pending transactions. Also, I have geth as local node.

So, do I have some issues with my local node or it is expected behavior?

I tried to increase txpool.globalslots parameter but it did not help me. I still have the same problem

Answer 1

It's to be expected that a single node can't retrieve all pending transactions, Blocknative suggests a miss rate of 1%:

In our analysis, a single node's mempool in a single geography will miss ~1% of all transactions during normal operating conditions. Under heavy transaction volumes, the percentage of missed transactions can vary greatly.
