Modifications/fork to SynScaleMM:
- Based on r8 revision, from Nov 19, 2010;
- Compiles from Delphi 6 up to Delphi XE;
- Some pascal code converted to faster asm;
- Some code refactoring, a lot of comments added;
- Added (experimental) medium block handling from 2048 bytes up to 16384;
- Released under MPL 1.1/GPL 2.0/LGPL 2.1 tri-license.

Our fork has even been merged with the main trunk of ScaleMM! :)

Here is some benchmark/testing results (details and source code are available in our forum).
This code calls a string function (s := 'SomeText'+IntToStr(value);)in an infinite loop, then calculate the average of count.

I tested this little benchmark with or without our SynScaleMM unit, and with Delphi 7, Delphi 2007 and Delphi 2010. 
Delphi 7 has our enhanced RTL patches over System.pas and SysUtils.pas.. and there is quite a difference here!

On my Core i7 with 8 cores (4 physical cores + HT), with MAX_THREADS = 100, here are the results:

The higher, the better, of course!

The big gain of Delphi 7 comes from the very optimized version of IntToStr() we used in our Enhanced RTL. And Delphi 2010 IntToStr() is even worse, because it calls System.@UStrFromPCharLen every time!

But in all cases, the gain obtained by our SynScaleMM unit is worth mentioning, and trying in your server application, for instance.
All free, since it's licensed under a MPL/GPL/LGPL tri-license.
