in reply to Perl Read-Ahead I/O Buffering

Have you tried read()? If the records are fixed length you could read in for a length * number rows and then split on the newline or read in a big chunk and add logic to keep a partial record from the end of the buffer and add to it on the next read.
while ( read($fh, $buf, $len) ) { @lines = split "\n", $buf; . . . }
It may be faster, worth a try.
