What's Causing Latency in My Switch?

Greetings,

I have a Netgear VLAN switch, and upon doing a sustained Ping test, I find that every 20 seconds the latency builds up to over 250ms over a period of 5 seconds, then reverts down to about 6 ms.  

What I really need to know is, how can I figure out WHAT is responsible for causing this latency?

I had the exact same problem with one of those.  Drove me nuts.  Try resetting the switch to factory defaults then reconfigure.  When you reconfigure, use the most simple VLAN design you can get away with.

How do you mean?  

I have two VLANs on one switch.

However, I have another VLAN switch which is connected to the main VLAN switch, all the ports are untagged on the secondary switch.  I'm wondering if that could be the problem....
