Good afternoon all,

We are wondering why we getting a slow speed on in our network.

The incoming supply is running at about 160 MBPS is measured by plugging a laptop straight into the incoming router i.e. on the outside of the DMZ whereas on a workstation we are getting about 60 MBPS.

The switches between the USG 60 W and our office are both running at gigabit and the wiring interconnects are a mixture of fibre and CAT7

Any thoughts team?

    With UTM feature enabled, traffics are thoroughly scanned by USG, it would have effect on performance.

    Good morning

    Thank you for your reply

    Really as much of a hit to knock the speed down by 50%?

    Hi @Dovetail_MD,
    It is possible when all UTM features are enabled.

    For better performance with UTM enabled, ATP-100W would be suitable for your site.

    Good morning

    Thank you - I guess we could use a simple firewall rather than one with modem facilities as we have a modem from our broadband supplier which does simple NAT

    But does this simplification really improve throughput?

    Best wishes

    Andy

    Hi @Dovetail_MD,

    The throughput will be higher  if it just runs as a pure NAT router without UTM services. However, your network will lose the protection from USG instead. It depends on what purpose you want to achieve in your network environment.

    You misunderstand

    The vendor's router does NAT - I'm asking if no NAT and perhaps no wifi on the ZYXEL inboard of that will help speed

    And perhaps if Zyxels had more processor grunt the hit of UTM would be less?

    By default this is on and limits your speed so try this

    @PeterUK, True, It will have performance improvement if we uncheck collect statistics. 
    @Dovetail_MD, UTM service is the most CPU power consuming application, even though if you only enabled the UTM function without NAT, the improvement will still be limited
