Zyxel USG 60 W throughput

Dovetail_MD

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?

Hi @Dovetail_MD,

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.

Hi @Dovetail_MD,

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

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.

Dovetail_MD

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

Dovetail_MD

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
