Hm. I'm not sure that doing 4 lookups of the same value from the same process and then discarding the first one is much of a demonstration.

It is effectively the same thing as doing this:

c:\test> perl -MDigest::MD5=md5_hex -E"printf qq[%s %07d\n], md5_hex($ +_),$_ for 1..1e6" >hstore c:\test > type hstore.pl #! perl -slw use strict; use Time::HiRes qw[ time ]; use Digest::MD5 qw[ md5_hex ]; my $table = do{ local( @ARGV, $/ ) = 'hstore'; <> }; my %cache; my $v = '9509342c6a6b283d07a3ce406b06eb1e'; my $val = ( $cache{ $v } ) //= $table =~ m[$v (\d+)$]; for ( 1 .. 3 ) { my $start = time; my $val = ( $cache{ $v } ) //= $table =~ m[$v (\d+)$]; printf "Time: %.9f\n", time() - $start; } c:\test> hstore Time: 0.000007868 Time: 0.000009060 Time: 0.000001907

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
