Search and Replace command (Perl or similiar)

HI,

Looking for Perl command to be written to do the following in high speed:

2133|test||1|0|

The desired export format is:
2133|test|\N|1|0|\N

So basically replace || => |\N| in very large UNICODE files. Sed is not working for that reason. I am thinking of PERL but suggestions are welcome. Script process time must be ultra fast
