Is there a way to force FastMM to release freed memory back to the OS? Using Delphi 2009 with buildin FastMM. Tried to change the build configuration to Release instead of Debug, but FastMM still keeps the memory instead of releasing it back. Back in Delphi 7, when you free something, it insta released it back to the OS. I know it might not be good for performance.

I have an application with about 10 DLLs. The program is made with C++Builder XE4 32 bit VCL. The DLLs are all created as VCL Dlls. When I include a call to a Dll using the code below the FastMM gives the ‘cannot be installed’ error seen below. How can I make FastMM work in an app which calls DLLs? Without the calls to the DLL functions FastMM4 works correctly. Is there a recommended way to setup DLL calls? FastMM4 cannot be installed since another third party memory manager has already installed...

I am using C++Builder XE4 with the VCL 32 bit platform. I have installed FastMM successfully into most of my projects but one project shows the error message below. I am running the program though the IDE in debug mode. I am not sure my project has a .dpr file which is a Delphi file. I have FastMM4.pas list as the top item in the Build Order for the Delphi files and FastMM4BCB.cpp as the top item in the Build Order for the C++ Files. What can I try to solve this problem? FastMM4 cannot be installed...

{----------------------------Public types------------------------------} type {Make sure all the required types are available} {$ifdef BCB6OrDelphi6AndUp} {$if CompilerVersion < 20} PByte = PAnsiChar; // <-- REMOVE COMPLETELY, PByte EXISTS IN D/CB 6+! ... {$ifend} ... {$else} PByte = PAnsiChar; // <-- PByte EXISTS IN D/CB 5, TOO! Not sure about D/CB 4, though... ... {$endif}

I have an application that takes some time to open due to significant preloading of lists from a database. I implemented a splash screen, opening it in the project source file. This is the code: begin Application.Initialize; Application.MainFormOnTaskbar := True; frm_SplashScreen := Tfrm_SplashScreen.Create(Application); frm_SplashScreen.ProgramName := 'Garrett Customer Relations'; frm_SplashScreen.CopyrightYear := 2016; frm_SplashScreen.SplashImageRes := 'SPLASHIMAGE'; frm_SplashScreen.ProgressMessage...

Sorry. The >> did not display as I expected. The access violation error occurs in the call to LogStackTrace.

Small correction - 64-bit was added to C++Builder in XE3 Update 1, not in XE2. However, the memory manager functions do use NativeInt in XE2, so please make sure FastMM4.pas is handling that correctly, a least.

FastMM4BCB.cpp does not compile in XE2+ 64bit

FastMM4, by default, on thread contention, when one thread cannot acquire access to data, locked by another thread, calls Windows API function Sleep(0), and then, if the lock is still not available enters a loop by calling Sleep(1) after each check of the lock. Each call to Sleep(0) experiences the expensive cost of a context switch, which can be 10000+ cycles; it also suffers the cost of ring 3 to ring 0 transitions, which can be 1000+ cycles. As about Sleep(1) – besides the costs associated with...

What do you think about an option to fill freed (not actually used) pages with zero bytes? This may improve performance under Windows, and also under VMWare and other virtual machine environments? For example, VMWare and HyperV calculate hash of memory pages, and, if the contents is the same, mark this page as "shared" inside a virtual machine and between virtual machines on the same host, until the page is modified. It effectively decreases memory consumption. Windows does the same - it handles...
