Hi All,
I am programming a Bloom Filter and need a high-performance way to allocate
and wipe large block of memory. I did the following test:
program getmem;
{$mode objfpc}{$H+}
uses epiktimer;
const
SIZE = 1024 * 1024 * 1024;
CNT = 10;
var
a: array of Byte;
p: Pointer;

The result is:
Using SetLength:

Hi,
Is it possible to do Cocoa GUI programming on Mac/OSX using FreePascal but
without objective-pascal mode/dialect? Just pure object pascal or delphi
mode. How do I access the Cocoa SDK (foundation, appkit, etc) from pascal
code? GUI programming without GUI IDE is fine with me as long as I

FreePascal/Lazarus are no longer Apple friendly like they used to be.
How was FPC more Apple friendly in the past than it is now?

It is also breaks one of the most important advantage of FreePascal:
cross platform language.
How will you be cross platform if you access Cocoa directly?

If you use SetLength the dynamic array consists not only of the array
data, but also of an information record in front of it. This will likely
lead to the data not being aligned correctly (FillQWord works best with

Would you mind to show the timings that you got for FillChar? :)
Using FillChar is always about 5% (or less) faster than FillQWord when
used with GetMemory, but will be around 20%-40% faster if the memory is
allocated by
