This then creates high latency and then will interfere with running processes.

In a lot of cases it is usually down to poorly written hardware drivers that don't perform quick enough and cause lag between process execution. Here lies the million dollar question, many factors can cause high latency. To see the problem visually you can use a DPC latency analysis program which will tell you when you have bad latency. When you have bad latency you will experience drop outs and degraded audio. This can be often seen with multimedia content like music or video. When there is high latency various problems can occurs, one of the main issues that are a side effect of badly managed DPC latency is audio problems. Latencies may have different meaning in different contexts. Latency is a measure of time delay experienced in a system, the precise definition of which depends on the system and the time being measured. This permits device drivers and other low-level event consumers to perform the high-priority part of their processing quickly, and schedule non-critical additional processing for execution at a lower priority. an interrupt handler ) to defer required but lower-priority tasks for later execution. To understand DPC latency, its important to first understand what the two terms mean on there own:Ī Deferred Procedure Call (DPC) is a Microsoft Windows operating system mechanism which allows high-priority tasks (e.g. Sadly many factors can cause latency spikes, the Atheros Ethernet Controller seems to be just one of them.

It is important to note that while the use of the official Qualcomm Atheros driver over the Dell OEM driver has helped people in this situation it is not a guarantee that it will solve you problem. If you don't know what DPC Latency is or are unfamilar with the problem being described, take a moment to read through this thread, it is seperated into logical headings and groupings to make it easier to pick out the key information. There is far more to the situation than this, but it is a summarized version of the events that have taken place over the months.

Since this point, it has been a community recommendation to install the Qualcomm Atheros drivers rather than using the outdated Dell OEM driver which is dated May 2011 for the Ethernet card in the XPS 15z. This driver was tested by several community members and it was found that latency spikes were reduced heavily. It was eventually discovered that the Atheros Ethernet Adapter could be attributed to the problem, after a newer Non Dell OEM driver was found for the Atheros 815X Family Ethernet Controller on a third party website. A lot of community activity was involved in trying to get to the bottom of this problem.

There are many areas which have been highlighted including Windows 7 and its lack of process interruption protection, Intel WiFi Drivers, Realtek Sound Drivers and other areas. The latency spikes are caused by unknown factors which have never been truly pin pointed to any certain area (and still haven't to this day). The original problem described in this thread is regarding latency spikes over WiFi on the XPS 15z. This thread has expanded massively overtime, so the information in its entirety might be difficult to take in without knowing all the facts. If you haven't followed this thread through various developments since it was first published, take a second to read this summary.
