My customer says it's slow at random times.

( He refuses to test with another color-schema, because he thinks it has
nothing to do with the problem... )

I don't use a sessionhandler I think...

This is in my horde conf.php:
$conf['session']['name'] = 'Horde';
$conf['session']['use_only_cookies'] = true;
$conf['session']['cache_limiter'] = 'nocache';
$conf['session']['timeout'] = 0;
$conf['sessionhandler']['type'] = 'none';
$conf['sessionhandler']['memcache'] = false;

Can this be the problem?
