IP Segment : Fast as admin, nothing as viewer

I’m experiencing a problem with Segments.

As a Piwik Superuser, using a segment that filter IP and is processed with Cron the results are almost instantly visible. The site got 100 000 pageviews a day.

Switching to a user with view only, I never get results using the same segment.

IMPORTANT: My Segment is filtering multiples IP and I’m aware of this patch I applied :

Any idea ?
