Hi,
I am working on an application that needs to manipulate big blocks of
data in memory, 50MB .. 500MB in size.
Are there any guidelines concerning which memory allocation mechanism is
a) the fastest, and b) least likely to fail on resource limited
machines? I can see at least the following options:
1) TMemoryStream
2) array of byte
3) GetMem
4) Alloc
5) GlobalAlloc
6) IStream
Any ideas?
Regards,
AndrewFG
