Please suggest alternative to grep

Hi Experts,
PFB my requirement:
I have a file (named file1) containing numbers like:
Code:
372846078543002
372846078543003
372846078543004
372846078543005
372846078543006

I have another file (nemed file2)where lines containing these numbers(present in file1) are present; Eg:
Code:
lppza087; [2012-06-05 03:00:01,090] <PERFB  > JMSId :ID:414d51204c50505a41303837202020204f657ff1299e7bb7 SvcName :realtime.get.relationship Port :Port1 LobId :AMCSGCDERTUSUSD Card :372846078543002 SrcCd :16 versionNum :3.0 OO [MessageListenerThreadPool : 11  ] OO dao.CustDAO                       OO                 getRelnDetails() OO Entry : getRelnDetails
lppza087; [2012-06-05 03:00:01,100] <PERFB  > JMSId :ID:414d51204c50505a41303837202020204f657ff1299e7bb7 SvcName :realtime.get.relationship Port :Port1 LobId :AMCSGCDERTUSUSD Card :372846078543003 SrcCd :16 versionNum :3.0 OO [MessageListenerThreadPool : 11  ] OO dao.CustDAO                       OO                 getRelnDetails() OO Exit  : getRelnDetails

I need to grep all those lines present in file1 from the other file (file2).
One way will be to run a for loop on file1 and grep in file2. But my data volume is very high an it's taking 5-6 hours.
Can you please suggest the fastest way to achieve this (may be using awk/sed)

NAME
mv - move or rename files SYNOPSIS
mv [ -i ] [ -f ] [ - ] file1 file2 mv [ -i ] [ -f ] [ - ] file ... directory DESCRIPTION
Mv moves (changes the name of) file1 to file2. If file2 already exists, it is removed before file1 is moved. If file2 has a mode which forbids writing, mv prints the mode (see chmod(2)) and reads the standard input to obtain a line; if the line begins with y, the move takes place; if not, mv exits. In the second form, one or more files (plain files or directories) are moved to the directory with their original file-names. Mv refuses to move a file onto itself. Options: -i stands for interactive mode. Whenever a move is to supercede an existing file, the user is prompted by the name of the file followed by a question mark. If he answers with a line starting with 'y', the move continues. Any other reply prevents the move from occur- ring. -f stands for force. This option overrides any mode restrictions or the -i switch. - means interpret all the following arguments to mv as file names. This allows file names starting with minus. SEE ALSO
cp(1), ln(1) BUGS
If file1 and file2 lie on different file systems, mv must copy the file and delete the original. In this case the owner name becomes that of the copying process and any linking relationship with other files is lost. 4th Berkeley Distribution April 29, 1985 MV(1)
