the reason transactions take so long is because of compliance. COBOL, CICS (the tramsaction manager) and mainframes themselves are constantly being updated and optimized because no flavor of the week in the last three decades has been able to handle the throughput needed by the companies that still use them. if anything in the tech stack at banks is slowing down your paycheck getting cashed, it’s the small army of nodeJS servers whose entire codebase gets rewritten every six months because some exec thinks COBOL isn’t sexy enough and we can get rid of it we say the word “agile” enough. the fortune 500 has been planning on being “off the mainframe in the next 3 years” since the 90s

In the meantime let’s fire up some AS400 (yes I know, it’s called IBM i or whatever now nobody cares)
My last company was selling IBMi’s and writing the code for them. Customer’s didn’t like our GUI product. They wanted rock-solid, green screen menus.
