Hi Alan,
When looking at the FileChannel.map() method, it seems that it will
not write "e" 4 billion times. Instead, it only extends the file size
to testSize+10. It uses ftruncate() in linux and uses SetFilePointer()
in Windows, which causes the file offset different on different
platforms. But the performance should be good. On windows, this test
runs for around 0.14 seconds in jprt machines. Thanks!
Okay, what you have is fine and in time we will see whether it reliable.
