We have a Fortigate FG200D behind a dirty switch. We upgraded our ISP bandwidth from 50x50 to 1Gbx1Gb.
With a device plugged into the dirty switch I speed test about 850x850 consistently.
Behind the firewall my speed tests are 500x100 consistently.
I have turned disabled all web filtering, AV, IPS, etc to test, and it doesn't make a difference filtering or not. Still the same degraded speed.
Anyone know what else I can test/check for the bottle neck?
