in thread Reading multiple lines?

would it faster just lynux/unix command line? tail $fileName -n $start | head -n $length where $start =100 and $length =10000-100 So that no readin file and thus not much memory used. I used this to fetch block of lines within a file with more than 100 million lines. Average time to get results was ~ 1 minute.
