I just wrote a tiny little script, just using DBI and DBD::SQLite, and
there is no delay.
#!/usr/bin/perl
use strict;
use DBI;
use DBD::SQLite;
my $recipes_sql = q/SELECT * FROM recipe/;
my $dbfile="/home/fiber/data/recipe.db3";
my $dbh = DBI->connect("dbi:SQLite:$dbfile") or croak $DBI::errstr;
my $recipe_ary_ref = $dbh->selectall_arrayref($recipes_sql,{ Slice =>
{} });
foreach my $recipe ( @$recipe_ary_ref ) {
print qq/$recipe->{ID} $recipe->{NAME}\n/;
}
Thanks!!

Are you sure you measure correctly?
Did you include Perl startup time by accident?

I'm just getting started using DBIx::Class and I am a little surprised
at performance (rather, lack there of).
Perhaps I've missed some key point, index or other such thing, but it
takes well over a second to get results on a single table that has
very few records (<20).
I am running on Debian Squeeze (Linux 2.6.33 i586) with perl (v5.10.1)
and SQLite3 (3.7.3).
If I export DBIC_TRACE=1 and then run the my script, I see this:
SELECT me.ID, me.NAME FROM recipe me:
So then if I run that query in sqlite3, it is markedly faster. I
understand that the DBIx::Class needs a little more time, this delay
makes me think I must have missed something.
Thanks!!
