Hi L~R,
You can input your data in benchmarking here.

My benchmark, comparing 200,00 records and each record contain a 50 fields containing small numeric data as key and value, gives the results:

Benchmark: timing 200000 iterations of with_tie, without_tie...
  with_tie: 98 wallclock secs (96.22 usr +  0.00 sys = 96.22 CPU) @ 2078.61/s (n=200000)
without_tie: 14 wallclock secs (13.25 usr +  0.00 sys = 13.25 CPU) @ 15094.34/s (n=200000)
               Rate    with_tie without_tie
with_tie     2079/s          --        -86%
without_tie 15094/s        626%          --
And the code is

use Benchmark qw(cmpthese); use strict; use Tie::IxHash; sub with_tie { tie my %menu, 'Tie::IxHash'; foreach (1..50){$menu{$_} = $_; } } sub without_tie{ my %menu; foreach (1..50){$menu{$_} = $_;} } cmpthese(200000, { with_tie => \&with_tie, without_tie => \&without_tie });
