With Bitcoin Core, I am looking at the mempool in my node and it is sitting at 3mb (1,809 transactions).

I am aware of transactions that are unconfirmed (visibile on explorers) but not on my node. Further to this mempool.space has a mempool size currently of 23mb 28,781 (unconfirmed transactions).


I am aware that every mempool is different, but is my core mempool artificially limited to be 1/8 the size of other mempools? Can I change this to have a fuller picture of the network/mempool/unconfirmed transactions?

DBCache is set to 8,000.
