XF 1.2 cache does not work properly

[imsory]

hello
I upgraded from version 1.1.3 to 1.2.2. And now, when I open a new page, I see a white page for 0.5 seconds. Previously, this was not. I have the feeling that the cache does not work properly.

Any help please.

Server: nginx + php fpm + apc

Settings:

$config['cache']['enabled'] = true;
$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions'] = array(
'caching' => true,
'automatic_serialization' => true,
'lifetime' => 14400,
'cache_id_prefix' => 'xf_'
);

$config['cache']['backend'] = 'File';
$config['cache']['backendOptions'] = array('cache_dir' => '/var/www/mysite/cache');
