Disk file to string array timings

[jj2007]

Hi folks,
I have done some changes to my string engine and would like to see a few timings. Source is attached, including a "bonus" (C64.asm) that compares Recall to the Masm32 library arrfile$ etc macros using a 64MB file (more).

      pop eax
   Next
   Inkey Str$("\n\n%i strings", eax), Str$(", %i bytes", LastFileSize)

end start

I really wonder how the same task would perform in another language - C or FreeBasic or PowerBasic...

Thanks, fearless. I should have normalised the result - your Win*incs seem to be a bit shorter...

Why "GenuineIntel".. you see this everywhere, even with AMD... I'm curious to know who's going to take the trouble to duplicate a processor this big  :bg

It's a Windows environment variable... where did you see GenuineIntel for an AMD processor?

PrintLine ExpandEnv$("%PROCESSOR_IDENTIFIER%")

[vanjast]

Sorry, I wasn't clear about the AMD thingy... "AuthenticAMD"

I see, I thought this might be buried in a CPU identification register..
:8)

[dedndave]

it is   :P

If you execute a CPUID instruction with EAX set to 0 the bytes in the EBX:EDX:ECX registers spell GenuineIntel, for AMD the EBX:EDX:ECX registers contain AuthenticAMD.
