I was recently asking the original author of Plutus about this same issue, he's since updated his code. There's a memory issue with loading the full database when only Legacy (P2PKH) addresses are the ones it checks. The segwit and legacy segwit addresses in the database only slow things down, please consider updating to one that only loads the addresses that begin with '1', unless your code checks all available and possible addresses. You check his recent commit for the changes he made. Thanks
