Now I'm trying to finish a script for sharing huge files (maybe 3Gb) in local network using remote drive under MSWin32. I found some helpful code at File copy progress., and in this code, the following statements make me puzzle : 
  my $blksize  = int ($filesize / 10);
  my $num_read = sysread(SRC, $buffer, $blksize);

[download]
That's how to decide the block size ($blksize) to get the best performance, and is that sensitive to file system, if I use my script under Linux, shall I modify the value ?
Thanks very much !
