i have an actual ~ 2GB file created. Here's my results
Code:
# time awk 'END{print NR}' twogigfile.txt
39810582

real    1m8.784s
user    0m10.297s
sys     0m3.056s
# time awk '{x++}ED{ print x}' twogigfile.txt
39810582

real    1m6.738s
user    0m15.365s
sys     0m3.044s

# time wc -l twogigfile.txt
39810582 twogigfile.txt

real    1m5.920s
user    0m2.716s
sys     0m2.952s

# time sed -n '$=' twogigfile.txt
39810582

real    5m33.276s
user    5m12.508s
sys     0m3.368s

wc is comparable to awk methods. sed and cat methods pales.

NAME

       bnmotd.txt, bnnews.txt bnissue.txt - messages for the Unix Battle.net daemon

DESCRIPTION

       The file bnmotd.txt contains text displayed by bnetd(1), when users first log into the server.

       The file bnnews.txt contains text displayed when the user uses the /news chat command.

       The  files  consist  of raw text with printf-style formatting escapes.  Each line of a file can contain a type formatter from the following
       list:

	      %B     Use the broadcast attribute (???).

	      %C     Execute the line as if the user entered it as a command.

	      %E     Use the error attribute (red).

	      %I     Use the info attribute (yellow).  This is the same was %W.

	      %M     Normal chat message (white).  This will appear as if the user said it.

	      %T     Emote chat message (???).	This will appear as if the user said it.

	      %W     Use the warning attribute (yellow).  This is the same was %I.

       Within a line, any of the following format formatters may be used:

	      %%     Expand to a literal percent sign (%).

	      %a     Expand to the number of accounts on the server.

	      %c     Expand to the number of channels on the server.  This includes all permanent and current temporary channels.

	      %g     Expand to the number of games on the server.  This includes both public and private (passworded) games.

	      %h     Expand to the hostname of the server (as returned by gethostname(2)).

	      %i     Expand to this user's account ID number, formatted with a leading pound (#) sign and leading zeros.

	      %l     Expand to this user's current chat name which is usually the same

	      %r     Expand to the IP of the remote machine (the client).

	      %t     Expand to four character client tag.

	      %u     Expand to the number of users logged into the server.

	      %v     Expand to the version number of the server.
