line count

Hello
I just need the line count of the file...
the file is too huge and cant count manually..
Of course i did
Code:
wc -l

But this simply got stuck..
Any suggestion...
Tried plenty of option, i know its easy, browsed the google but was not satisfied...

Below commands also will give the line count, but no idea about its perfomance.

Code:
grep -c "\n" filename

Code:
awk 'END {print NR}' filename

Both the commands gave me same output in small file. But I think awk is accurate than grep.

Not sure about the performance. But you can check the other options available here: Different ways to count total lines in a file.
