The compiler is compiling million of lines of code in my project although I have less than 10K lines of code. My problem is with the sometime long delay in Code Completion. I remember there's a trick to delete some files in the BCB directory but I can't find it on the web anymore. All solutions welcome!

All solutions welcome! The trick you are referring to is to delete all the .hdp files. Apparently these were an attempt at automatically making precompiled headers for small projects that quickly turn into a slow-down as the project grows. The other important thing to do is to optimise your precompiled headers. For precompiled headers to work well, you need to include EXACTLY the same sequence of headers before the #pragma hdrstop in EXACTLY the same order, in EVERY file in the project. I do this by creating a specific header file for each project that includes all the headers I want precompiling, and use that as the ONLY header before the #pragma. I also set each project up with its own precompiled header file in the project options. Both of these help, but I find code insight/completion are still very slow in BCB. The various technology demonstrations that have been seen for BCB in Delphi2005 (at Borcon and BDNTV) show that this should be considerable faster in the next release - although we still have no idea how long that wait will be.

I can feel that the compilation was a bit faster too but I didn't had a baseline. The only problem are sources with a Form which takes 4-5 secs to bubble the CodeInsight. I had a feeling that it is parsing the headers each time as the CPU is 100% for full 5 secs. "Alisdair Meredith" wrote in message news:4243c47e$1 (AT) newsgroups (DOT) borland.com...

Before I got a new PC (AMD64, 3400+, MSI K8N Neo), I disabled all CodeInsight features, because it was attacking my nervs because of slow-downs and BCB hangs-up. Now, Code Insight works OK, and I haven't disabled it (yet). -- Best regards, Vladimir Stefanovic Back to top Andrue Cope [TeamB] Guest Posted: Wed Mar 30, 2005 8:13 am    Post subject: Re: Speed up BCB Compilation Yakov, Could you trim your quoting please?

You might be using a newsreader that automatically surpresses signatures. If all you can see is Yakov's reply then you are. Unfortunately underneath his signature he has a copy of the original message with the addition of '>' characters at the start of every line. The problem with this is that 90% of Yakov's reply is a copy of text that is freely available on the newserver in its original form should anyone need to review it. The result is that the original message is being stored on the server twice (which wastes disk space) and perhaps more importantly has been transmitted twice as many times as was needed thus wasting bandwidth. Borland operate this newserver and they have guidelines (http://info.borland.com/newsgroups/guide.html if you can't see my signature). These ask that users keep quoting to a minimum and I as a member of TeamB am a moderator and I try to ensure people keep to Borland's rules :) -- Andrue Cope [TeamB] [Bicester, Uk] http://info.borland.com/newsgroups/guide.html Back to top Yakov Becker Guest Posted: Thu Mar 31, 2005 12:09 pm    Post subject: Re: Speed up BCB Compilation Sorry for including original e-mail text in my response. Can you explain why compiling from the command line 10 times faster than from IDE? Thanks, Yakov Becker Back to top tinyabs Guest Posted: Thu Mar 31, 2005 12:52 pm    Post subject: Re: Speed up BCB Compilation Perhaps without the IDE, it has more memory to work with; no memory swapping.

Sorry but I find it a bit of a mystery as well :) I've been told that it's mainly due to memory usage but I find this puzzling. I can't immediately see any reason for the memory usage to be significantly different just because the compiler is being called from the IDE. I can run the command line compiler from a separate console when one or more IDEs are open and it runs at the same lightning fast speed. Perhaps there's an overhead in the compiler communicating progress information back to the IDE but that is even more hard to believe. I've done that kind of thing myself and the performance reduction is negligable. -- Andrue Cope [TeamB] [Bicester, Uk] http://info.borland.com/newsgroups/guide.html Back to top Alex Bakaev [TeamB] Guest Posted: Thu Mar 31, 2005 5:33 pm    Post subject: Re: Speed up BCB Compilation Andrue Cope [TeamB] wrote: Quote: Yakov Becker wrote: Can you explain why compiling from the command line 10 times faster than from IDE?

Can you explain why compiling from the command line 10 times faster than from IDE? I would strongly suspect a bug, which only becomes noticable with large projects. I looked into this some years ago (see http://tinyurl.com/3fqlq for some findings). I don't know if this is still the same problem, but I would suspect that it is. Makefiles seem to be the only solution for large projects.

I removed most of the packages in "Install Packages" section, leaving only some JVCL and BCB standards design packages. CodeInsight now takes a maximum of 3 seconds now, down from 5 secs. The memory usage is 50-70MB, down from 70-80MB. However, the compilation time didn't not changed much. I tuned the disk cache and only got 2 secs off it. Yeah, my problem solved.
