Performance Issues on 10.0.0.0/8

I was called to help out a local church with some significant network stability problems; intermittent speed, timeouts, etc. Fairly large, they see around 800-1000 people in a service. Started digging around and discovered they were set up on a 10.0.0.0/8 subnet - I know this makes ARP attacks pretty easy, but could 16 million possible IPs be contributing to the network instability?
