fastcgi + perl

[tem]

os: freebsd7.0, amd64

nginx-0.7.65
perl5.10.1 + CGI::Fast FCGI FCGI::ProcManager

процессы перловые висят в состоянии sbwait:

замеряя где зависания по поводу открытия сайтов нашел, что висит в месте print.
то есть до него и после замеряю Time::HiRes::time(); и вывод.. плохой.

[code]
while(my $q = CGI::Fast->new()) {
	pm_pre_dispatch();
        my $buf = &build_buffer($q);
        my  $time0 = &Time::HiRes::time();        
        print $buf;
        my  $time1 = &Time::HiRes::time();
 	pm_post_dispatch();
        print LOG "$$: outtime = ".($time1 - $time0)."\n";
}
[/code]


$buf размером от 120к до 240к

играясь с 
[code]
  fastcgi_buffer_size 128k;
  fastcgi_buffers 8 32k;
  fastcgi_busy_buffers_size 128k;
[/code]

особой разницы в статистике вывода не заметил.

откуды эти 5-15 секундные зависания?
и как их победить?
