Fortigate 61E High Memory Usage

[Lucas_Piris]

Hi,

We have a problema with a Fortigate 61E with 110~120 users.

FortiOS: 5.4.5

With:

Webfilter

Aplication Control

IPS

SSL Inspection

The customer have Three links, one of 20mbps full, and two others of 10mbps each, for failover only.

But, the Fortigate 61E, is not supporting the traffic, about 110~120 users.

So, this numbers, are fake?

Firewall Throughput (1518 / 512 / 64 byte UDP packets) 3 / 3 / 3 Gbps Firewall Latency (64 byte UDP packets) 3 μs Firewall Throughput (Packets Per Second) 4.5 Mpps Concurrent Sessions (TCP) 1.3 Million New Sessions/Second (TCP) 30,000 Firewall Policies 5,000 IPsec VPN Throughput (512 byte packets) 2 Gbps Gateway-to-Gateway IPsec VPN Tunnels 200 Client-to-Gateway IPsec VPN Tunnels 500 SSL-VPN Throughput 150 Mbps Concurrent SSL-VPN Users (Recommended Maximum) 100 IPS Throughput (HTTP / Enterprise Mix) 1 1,400 / 350 Mbps SSL Inspection Throughput 2 340 Mbps Application Control Throughput 3 550 Mbps NGFW Throughput 4 250 Mbps Threat Protection Throughput 5 180 Mbps CAPWAP Throughput 6 1.5 Gbps Virtual Domains (Default / Maximum) 10 / 10 Maximum Number of FortiAPs (Total / Tunnel Mode) 10 / 5 Maximum Number of FortiTokens 100 Maximum Number of Registered FortiClients 200 High Availability Configurations Active / Active, Active / Passive, Clustering

The TAC cannot explain why, and  I need to understand.

Anyone can help me?

Regards

How did you resolve this. i have two 61E with each around 20 people but still cannot support them. the memory is almost 70 percent when no one is even in the office.
