BIG-IP VPR-B4450N max connections support

Hi we need to know what is the maximum number of connections that the BIG-IP VPR-B4450N card supports. We currently have it in balancer mode for TCP/UDP connections to servers behind the f5. The connections are DNS requests. We want to know how many connections per second it supports. We understand that this information is in the F5 documentation but it is not clear to us if we are understanding it correctly. Currently the F5 reports 600K New connections for second.

Thanks a lot.
