I'm not convinced that those are real benefits. Out of line inlines (debug) produce smaller, less buggy(if you use the STL) code. As for speed, Borland' optimizer kinda sucks anyway.

The debug symbols are already removed by the linker and stored in a TDS file. I guess I could undefine _DEBUG to get rid of the ASSERTS and so forth.

Regards, Bruce I think the definitive answer is 'maybe'. As you've said, the debug symbol info is in the TDS file. You can disable inline expansions in release mode if you like. I've done some performance testing on BCB5 and VC++ 8 (VS 2005 beta) in both debug and release mode. My app is likely not similar to yours, so you mileage may vary. In any case, I found BCB release mode to perform somewhat, though not terribly, faster than debug mode. The VC++ compiled app was probably at LEAST 4-5 times faster in release mode. VC does a lot more work in debug mode, including setting patterns into allocated buffers. This takes time. It's probably more like a BCB app running with Code Guard. For reference, the app was DB orientated and did a lot of I/O. But, then, using ADO/OLEDB it was probably doing a lot of memory [de]allocation also. I haven't tried a more CPU-intensive app. I wouldn't lose sleep over it. You can have some confidence that if it runs for you in debug mode, it'll probably run the same in the field. But if you build and test in debug and then build and ship in release, who knows. We've certainly had a few problems there. - Arnie Back to top Bruce Salzman Guest Posted: Tue Mar 08, 2005 8:06 pm    Post subject: Re: Debug vs. Release Build Quote: I wouldn't lose sleep over it.

We've certainly had a few problems there. That's mainly what I was worried about, a bunch of release mode bugs that I haven't seen before. Plus it's such a PITA to rebuild in debug mode to track down a bug report, that I will probably stick with the debug mode.
