Do you mind adding a stored procedure to your benchmark? E.g. something like: 
-- db2 -td@ -f proc_get_data.sql
CONNECT TO VIPER
@

DROP PROCEDURE PROC_GET_DATA
@

CREATE PROCEDURE PROC_GET_DATA
(
  IN  pi_name     VARCHAR(32)
)
  LANGUAGE SQL
  SPECIFIC PROC_GET_DATA
  NOT DETERMINISTIC
  NO EXTERNAL ACTION
pgd: BEGIN
  DECLARE v_name      VARCHAR(32)   DEFAULT '';

  DECLARE c_trans CURSOR WITH RETURN FOR
    SELECT * FROM TABLE WHERE NAME = v_name;
  SET v_name = pi_name;

  OPEN c_trans;

END pgd
@

COMMIT WORK
@

CONNECT RESET

You should be able to do the same comparison (bind vs. no-bind ) there: 
use strict;
use warnings;

use Benchmark qw (cmpthese);
use DBD::DB2;
use DBD::DB2::Constants;

my $dbh = DBI->connect("DBI:DB2:viper", "db2inst1", "foobar");
defined($dbh) or die "Unable to connect to database:" . $DBI::errstr;

sub proc_bind {
  my $stmt = "CALL PROC_GET_DATA(?)";
  my $sth = $dbh->prepare($stmt) or die "prepare failed";
  $sth->bind_param(1, "abeamish");
  $sth->execute() or die "Execute failed:" . $DBI::errstr;
}

sub proc_no_bind {
  my $stmt = "CALL PROC_GET_DATA(?)";
  my $sth = $dbh->prepare($stmt) or die "prepare failed";
  $sth->execute("abeamish") or die "Execute failed:" . $DBI::errstr;
}

cmpthese(
  -1,
  {
    'proc_bind'    => sub { proc_bind },
    'proc_no_bind' => sub { proc_no_bind },
  }
);

__END__

The difference between the two is not measurable at my local system (note that the table had 0 rows so the numbers do not compare to yours): 
$ perl -w 687634.pl
               Rate    proc_bind proc_no_bind
proc_bind    1569/s           --          -3%
proc_no_bind 1615/s           3%           --

(Having a table named table is slightly confusing, to say the least, but apparently valid in DB2 :)

No matter how great and destructive your problems may seem now, remember, you've probably only seen the tip of them. [1]
