Re: Debug slows program by a factor of 30?

While it is almost inevitable that RDi debug is a little slower (extra comms traffic if nothing else) the usual reason for poor performance is that the Variables tab is visible. Under those circumstances each and every variable in the current call stack entry is potentially being updated with each step. In a subprocedure with a dozen variables that is no biggie. In a typical RPG monolith it is a huge overhead. It can be "cured" by the size expedient of making sure that the Variables tab is not in focus.

Would you expect the green screen to behave the same way? While I love the RDi debugger, I have observed very poor performance when using it.

Justin - yes, I think CGIDEV2 and HSSFCGI use Java calls to create spreadsheets on the IFS, which is what this program is doing.

That's pretty much what I would expect. I can't recall how the internals work but the fact that you only have one breakpoint doesn't stop the system from seeing every statement as a potential break.

I was debugging a program that calls CGIDEV2 and HSSCGI to create Excel files... in debug, it took the program over an hour to complete. I had one breakpoint where I checked one variable, then F8 to continue.

Call the same program w/out debug and it completes in less than 2 minutes.

I'm on version 9.5 (thankfully), and connected Ethernet to our system on the same network.

Any ideas?
