Throughput issues in Cisco ASA 5510

For internet connectivity, we have a Cisco Firewall connected to a BGP router multihomed with 2 ISP. Attached the high level diagram for reference.

We have noticed that the bandwidth usage over the primary connectivity is less than 5 % of the total 100 mbps internet bandwidth, same way if i route the traffic via the secondary path then the bandwidth goes at an average up to 30 %.

I have noticed that if i use any fast download softwares like DAP, then i am getting a speed of almost 10 Mbps but the normal usage is not crossing 5%. Is there any settings in ASA that i have to do to make this primary interface use more bandwidth.

Throughput issues in Cisco ASA 5510

It looks like only the http traffic that is not giving the throughput, the VPN and all other traffic is perfectly working. Also as i mentioned earlier if we use a Download Accelerator then i can easily download with 10 Mbps speed.

Any idea is this behavior due to any inspection ?

Please check the below configuration, any idea will this impact the internet browsing and download rate.

class-map netflow-export-class

match access-list netflow-export
