Because I haven't set up many include directories yet, the time difference with an updated patch are not that high New VCL Application - Build: Without patch: 3.06 ms With patch: 2.97 ms But that is not a valid testcase. Unfortunatelly I cannot compile my "testcase" (aka qmake.exe) due to the new compiler. I think I must remove many #ifdef Q_CC_BOR from Qt4 now. -- Regards, Andreas Hausladen Back to top Sean Hoffman Guest Posted: Sat Dec 10, 2005 11:02 pm    Post subject: Re: Speed bug also exists in BDS 2006 Andreas Hausladen wrote: Quote: The Compiler<->IDE bug that increases the compile time also exists in BDS 2006 (my copy arrived today). snip So is the patch the same for the new compiler or different one?

Yes, except the .bpl name and the symbol from where I get the original callback structure. But I'm still testing. And maybe I port my file caching from bcc32pch to the IDE Compiler Speed Improvement patch. -- Regards, Andreas Hausladen Back to top DavidPerkins Guest Posted: Sat Dec 10, 2005 11:50 pm    Post subject: Re: Speed bug also exists in BDS 2006 Quote: The Compiler<->IDE bug that increases the compile time also exists in BDS 2006 (my copy arrived today).

Meanwhile, It would be good to add your fix as a workaround for QC13775 And - please *all* vote for QC13775 so we can get Andrew's fix applied to BDS2006 ASAP... - Roddy Back to top Dennis Jones Guest Posted: Mon Dec 12, 2005 4:36 pm    Post subject: Re: Speed bug also exists in BDS 2006 "Andreas Hausladen" <AndreasDOTHausladen (AT) gNOMAILmx (DOT) de> wrote Quote: The Compiler<->IDE bug that increases the compile time also exists in BDS 2006 (my copy arrived today). Because I haven't set up many include directories yet, the time difference with an updated patch are not that high New VCL Application - Build: Without patch: 3.06 ms With patch: 2.97 ms First, I assume you meant s, not ms. Second, no two builds take the same amount of time even when several builds are executed in succession, and especially for such a small project. That small of a difference (0.09s) can easily be chalked up to variability in running background processes, disk caching, and a myriad of other variables. A *much* larger project would be a better test case. - Dennis Back to top Andreas Hausladen Guest Posted: Mon Dec 12, 2005 6:35 pm    Post subject: Re: Speed bug also exists in BDS 2006 Dennis Jones wrote: Quote: First, I assume you meant s, not ms. Yes. Quote: Second, no two builds take the same amount of time even when several builds are executed in succession, and especially for such a small project. That's right. I tested it with a much larger project (but first I had to remove some #ifdef Q_CC_BOR from Qt4) The a counter speaks words: FileOpen: execution count: 106016 passed to original FileOpen: 9896 FileAge: execution count: 4937 passed to original FileAge: 349 Compiled with original Compiler: 30.66 secs Compiler with IDE Compiler Speed Fix: 22.80 secs Compiler with bcc32pch's IDE Compiler Speed Fix: 19.41 Compiler with bcc32pch using bcc32ide: N/A (development not finished yet) I seems that Borland has optimized their FileOpen a lot becaue BCB 6 would have taken minutes if it would have to ("try-") open 106016 files. I think the time difference comes from the hashtable that Borland does not use. The 3 seconds from bcc32pch are header file caching. This consumes a lot of memory so I introduce a new option "Enable header file caching during compilation". -- Regards, Andreas Hausladen Back to top Roddy Pratt Guest Posted: Mon Dec 12, 2005 7:38 pm    Post subject: Re: Speed bug also exists in BDS 2006 "Andreas Hausladen" <AndreasDOTHausladen (AT) gNOMAILmx (DOT) de> wrote Quote: Compiled with original Compiler: 30.66 secs Compiler with IDE Compiler Speed Fix: 22.80 secs Compiler with bcc32pch's IDE Compiler Speed Fix: 19.41 Compiler with bcc32pch using bcc32ide: N/A (development not finished yet) I seems that Borland has optimized their FileOpen a lot becaue BCB 6 would have taken minutes if it would have to ("try-") open 106016 files. Can you get a comparable time for BCB 6? On this basis, it seems that Borland have actually "fixed" the problem, even though they don't claim to have. I guess you're right about the hash tables. They might be persuaded to implement something like that to get a 30% speed improvement, but it's nothing compared to the 3x+ improvement that's already been addressed. Assuming they *have* fixed it, I'm amazed they haven't talked up the new performance. For many shops, that fix alone would justify the upgrade costs in a matter of weeks. Or maybe it got fixed so long ago that they've forgotten....? Can we tell anything by inspecting FileOpen in the VCL source? BCB5 FileOpen just calls CreateFile... - Roddy Back to top Andreas Hausladen Guest Posted: Mon Dec 12, 2005 8:17 pm    Post subject: Re: Speed bug also exists in BDS 2006 Roddy Pratt wrote: Quote: Can we tell anything by inspecting FileOpen in the VCL source? BCB5 FileOpen just calls CreateFile... The FileOpen alone was never the problem. It was the code around it that implements the virtual file system for the opened files. And without IDE source code we will never know if they fixed it. -- Regards, Andreas Hausladen Back to top Zach Saw Guest Posted: Tue Dec 13, 2005 8:29 pm    Post subject: Re: Speed bug also exists in BDS 2006 Quote: Compiler with bcc32pch using bcc32ide: N/A (development not finished yet) Do drop us a line when you're done with this. :) Back to top Andreas Hausladen Guest Posted: Tue Dec 13, 2005 8:50 pm    Post subject: Re: Speed bug also exists in BDS 2006 Zach Saw wrote: Quote: Do drop us a line when you're done with this. bcc32ide is on a hold until I have identified all the bug in bcc32pch that do not happen on my machine. -- Regards, Andreas Hausladen Back to top Zach Saw Guest Posted: Wed Dec 14, 2005 3:04 am    Post subject: Re: Speed bug also exists in BDS 2006 Quote: Do drop us a line when you're done with this. :) bcc32ide is on a hold until I have identified all the bug in bcc32pch that do not happen on my machine.

No because there is no bpr2mak.exe (or bdsproj2mak.exe) that I could call for creating the make files.
