Performance Specs for FortiWeb 600D

Does anyone have performance specs for FortiWeb appliances... especially the FortiWeb-600D. I find it funny that there are no detailed specs other than the throughput as compared to other Fortinet products.

Specs like: 1) Max HTTP Transactions

2) Max HTTP Connections

3) Max Concurrent Sessions

4) Max HTTPS Transactions

5) Max HTTPS Connections
