10 July 2026 added support for Windows 32bit (tbbmalloc)
(please update to latest visual c++ redistributable if not using static libs)
23 July 2026 Linux tbb parallel queue static lib (check the sample folder)
24 July 2026 Linux tbbmalloc static lib (no dependencies, no stripping, clean, dext qc test passed)

Dext a modern Delphi web framework tested with internal benchmark (vm windows 2025 intel 9900kf 8/16)

About zlib IPP accelerated: you can use symbolic name Z_IPP_FAST_COMPRESSION which is equal to -2
Introduced new sub-ranges of compression levels from 11 to 29
The standard levels 1..9 are compatible with original Zlib
Levels 11..19 are similar to 1..9, but fit better when compressing large files (more than 1 MB)
Levels 21..29 are for highly compressible files with compression ratio equal to 30x and higher

If you want enable accelerated zlib programmatically into your WebBroker app, just add one line of code in afterdispatch event:

• procedure TWebModule.WebModuleAfterDispatch(Sender: TObject; Request: TWebRequest; Response: TWebResponse; var Handled: Boolean);
• begin
• Response.ZlibDeflate;
• end;

The library is well tested, run on Intel and Amd x64 Windows, if you found any trouble please notify me;
big thanks to the Delphi community and its great coders, in particular for the support received from Bruno Fierens TMS and Daniele Teti DMVC.
