We are using hosted Microsoft Dynamics CRM. Our main internet connection is a 50 MB fiber connection with 24 ms of latency to the host. The fiber is <10% loaded. The Microsoft CRM takes 8 minutes to load the main page.
Our secondary ISP is a 6 MB DSL connection with 56 ms of latency to host. The DSL is <5% loaded. Microsoft CRM takes 15 seconds to load.
The fiber goes out a Cisco ASA. The DSL uses a Sonicwall.
The same issue is exhibited on all computers.
