i have a file containing over 1 million records,and i want to print about 300,000 line containing a some specific words.

file has content.
eg

Code:

1,rrt,234
3,fgt,678
4,crf,456
5,cde,drt
6,cfg,123

and i want to print the line with the word fgt,crf

this is just an example,my file is so huge,i have tried using

Code:

grep fgt filename

and

Code:

awk '/fgt/' filename

but it is so slow
is there a way where i can get the data faster
