while would be faster that foreach, after all I presume that you will 
need to read the file anyway.

while (<DATA>)
{
@itemarray = split (/\t/, $_);
   if ($itemarray[0] eq $searchitem) { do something... }
}

2000 records should not present a problem as far as speed unless your 
$item is very large.
