XPS 8950, upload speed via Ethernet cable slow

Question

My one month old XPS 8950 upload speed is slow compared to my old Optiplex 7010. Both are connected to the same modem via Ethernet cable. My XPS 8950 download and upload speed are: 923.8 Mbps and 2.4 Mbps My old Optiplex 7010 download and upload speed are: 930.1 Mbps and 929.3 Mbps My internet provider is Telus and Telus has been checking for the last two days and found nothing wrong with them and suggest me to call Dell . I call Dell and Dell said the problem is a software problem so I will have to pay Dell to solve the problem. Please give me advise. Should I pay Dell for the problem or should I return the one month old XPS 8950 to Costco because a defect desktop? Please not that I just have to reset the desktop because of the sound problem with the help of Dell Assist . Thank you for your input. Hop P

Sometimes, it's easy to miss a step. You don't delete apps. Go over and disable all Killer's in services and startup (task manager). Restart machine and check upload speed again. XPS 8950 user managed to fix it here.

I am glad that your issue get resolved. When your machine receive update drivers from Intel (pushed by Microsoft), it will restore the settings back. You will have to disable the services setting again if the issue comes back.

While I do setup machines with both Killer LAN and Wi-Fi (XPS and Alienware), the throughput performance is excellent without having to disable any services. My guess is, I do not install any of Dell utility apps in these systems, therefore, no conflict with Killer's analytics and services. The bandwidth is always maximized.

Because Dell uses utility tools, in combination with Killer apps.  Disable their services had helped other users.  Discussion here, here, and here.
