Setting up brand Dell machines with onboard Realtek Gigabit network adapter connected to Dell Powerconnect 2848 switch. We were noticing spikes in ping rates from workstations to server. We connected a Netgear 10/100 switch and all was working fine, so we thought we had a bad switch and had it replaced by Dell.
Got the new switch in and ended up with the same results. Contacted Dell Support but wasn't really getting anywhere. We discovered a setting for the network card called Inerrupt Moderation and disabled the setting. After disabling this setting ping rates were normal.
Through a little searching on the Internet it appears by disabling this we can sacrifice processor usage and with it enabled sacrifice network transmission. Looking at other computers purchased within the past year we don't see this setting on any cards.
Can someone explain what this setting is acutally for and why you would need it on a workstation?
Is there something different that needs configured with network switches to work with this feature?
This only seemed to happen when we were connected at Gigabit speed and to server and web filter only, why?
Would this affect streaming from the Internet?
Anything else or opinions?
