I have a pair of ASA5515-X's with firepower modules installed. They are managed by an FMC1000 appliance.
Each time I send traffic through the firepower unit my client experiences a huge slowdown in backup traffic.
The backup traffic is from between two servers on the same subnet so I would assume that we are not inspecting traffic in the same network.
I have added some ACLs to stop the "server" network to the "server network" from going through the sfr but still get the same results.
FMC ver 6.2
SFR ver 6.1
Please let me know what other details you may need in order to point me in the right direction.
Did you verify the flow through the ASA using packet-tracer?
packet-tracer input <server network interface nameif> tcp <server a address> 1234 <server b address> <tcp port used for backup application>
