[Openinteract-dev] benchmark seems not good?

[forehead<for...@4r...>]

hi, openinteract-dev

in apache cgi envriment, the first page [URL:/] gets:
   the code took: 5 wallclock secs ( 1.73 usr 0.23 sys + 0.00 cusr 0.11 csys = 2.06 CPU) 
   the code took: 4 wallclock secs ( 1.76 usr 0.22 sys + 0.00 cusr 0.11 csys = 2.09 CPU) 

and same code under mod_perl gets:
   the code took: 1 wallclock secs ( 0.46 usr + 0.07 sys = 0.53 CPU)   # fisrt request
   the code took: 0 wallclock secs ( 0.16 usr + 0.01 sys = 0.17 CPU)   # later request


apache 1.3.26 with mod_perl 1.26

in cgi mode, it seems need more time to init, process, I still not clear which phrase is the time-cost-est
still no idea about cache's effect.

some optimize policy?

# cgi-bin/oi2.cgi
#================
use Benchmark;

    
{
    # benchmark start tag
    my $t0 = new Benchmark;

	....

    $response->send;

    # benchmark end tag
    my $t1 = new Benchmark;
    my $td = timediff($t1, $t0);
    print "the code took:",timestr($td),"\n";
}


# Apache::OpenInteract2.pm
#=========================

use Benchmark;

sub handler($$) {
    my ( $class, $r ) = @_;

    # benchmark start tag
    my $t0 = new Benchmark;

	....

    $response->send;

    # benchmark end tag
    my $t1 = new Benchmark;
    my $td = timediff($t1, $t0);
    print "the code took:".timestr($td)."\n";
    
    return $response->status;
}
