:func:`shutil.copyfile`, :func:`shutil.copy`, :func:`shutil.copy2`,
|
|
:func:`shutil.copytree` and :func:`shutil.move` use platform-specific
|
|
fast-copy syscalls on Linux, Solaris and macOS in order to copy the file
|
|
more efficiently.
|
|
On Windows :func:`shutil.copyfile` uses a bigger default buffer size (1 MiB
|
|
instead of 16 KiB) and a :func:`memoryview`-based variant of
|
|
:func:`shutil.copyfileobj` is used.
|
|
The speedup for copying a 512MiB file is about +26% on Linux, +50% on macOS and
|
|
+40% on Windows. Also, much less CPU cycles are consumed.
