Most of the time the app really is fast. These old cobol apps have character limits per a screen for the amount of code you can use. Imagine each screen being like 200 lines of code with some raw storage behind the scenes. I had to performance tune a 3270 (mainframe) emulator once in c# and it took 2-3 weeks to get the c# app on a xeon processor to have to start waiting on the mainframe. Also nothing, ever, ever, timed out, ever. |
