bandwidth speed issue on NSA 2600
Our ISP provides us 1GB of data to our building & this has been tested & verified on their router. When I do a speed test on our firewall I only get 339 Mbps download & 664 Mbps upload when hardwired into my firewall during off peak hours. We do not have any
other functions enabled such as content filtering, antivirus, antimalware, ect., DPI is set to "DPI services enabled with additional performance optimizations". MTU setting is set to 1500 which ISP verified is correct. Any ideas what I can look at to figure out why we aren't getting our full speed? The NSA 2600 has a throughput of 1.9 GBps according to spec sheet.
