Hi Sven and all, I have a PostgreSQL database running in a resource-light Linux VM with ~4 million rows consisting of mostly text. My query executes regexp_matches() on the text and it runs noticeably slowly. I am encountering ConnectionTimedOut using P3 to run my query. PostgresV2 and Python's pg8000 do work though. I see that PostgresV2's PGConnection uses "Socket standardTimeout". I changed ZdcSimpleSocketStream class-side's #openConnectionToHostNamed:port: bottom part to add the same timeout because P3Client>>open calls it: ZdcSimpleSocketStream class>>openConnectionToHostNamed: hostName port: portNumber [...] ^ socketStream timeout: Socket standardTimeOut; "<== added this line" connectTo: hostIP port: portNumber; yourself Now my query returns instead of timing out. It does look like ZdcSimpleSocketStream's three class-side methods could use some refactoring love. Pierce
