Hi Monks,

I have noticed that perl reads minimum of 8KB (at least on windows64bit NTFS) whenever try and read after seeking. I would like to turn this down to a single 512byte LBA if possible to (hopefully) boost performance. Can this be done? Or is it OS/FileSystem dependent?

Example of this situation:

open my $fh, "<" , "reallyBigBinaryFile.bin";
binmode $fh;
my $offset = 0;
$/ = "~END"
while (1)
{
   seek($fh,$offset);
   $record = <$fh>; # Windows and drive show 16x 512b LBAs read here
   # length $record is 16 to 64
   $offset = newOffset($record);
}

In reply to Perl reads minimum 8KB from files. Can this be lowered? by sectokia
