If you believe you've optimized your Delphi application to the max, and there is no room for performance improvement, then you should check out following site: http://sourceforge.net/projects/fastcode

Project Fastcode is competition of assembler developers on rewriting certain Delphi RTL functions to processor-specific code, utilizing extra instruction sets like SSE, SSE2, etc. This way Fastcode winners achieve 2x-4x performance boost compared to classic i386 implementations.

Each function in Fastcode project has 5 variants, each variant is optimized for certain processor architecture:

• {function_name}_Blended - optimized for <= Pentium processors (employs i386, MMX instruction sets)
• {function_name}_Pentium3 - optimized for Pentium 3 processors (employs i386, MMX, SSE)
• {function_name}_Pentium4Northwood - optimized for Pentium 4 processors, Northwood kernel (employs i386, MMX, SSE, SSE2)
• {function_name}_Pentium4Presscot - optimized for Pentium 4 processors, Presscot kernel (employs i386, MMX, SSE, SSE2, SSE3)
• {function_name}_AthlonXP - optimized for Athlon XP (employs 3D-Now)
• {function_name}_Opteron - optimized for Opteron (employs ???)

I have put together a package allowing you start on using Fastcode just in 5 mins. It contains units that auto-determine your CPU type and auto-patch VCL to use Fastcode. The following Fastcode functions are included:

• Move - 200% performance boost
• FillChar - 200-400% performance boost
• Pos - 200-300% performance boost
• CompareText - 200% performance boost

I recommend using this package in non-GUI application servers, facilitating strong memory usage, etc.

Despite it will not make your application incredibly fast, overall speed up will be about 5%.
