Dpc latency what is

LatencyMon has been analyzing your system for h:mm:ss on all processors. Note: reported execution times may be calculated based on a fixed reported CPU speed. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution. NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Process with highest pagefault count: searchindexer. Care to be more specific about the problem instead of pasting useless latency monitor data. You are on win 8. You need to update to win 8. Ar you overclocking? I'm on windows 10 and i know that i'm getting dpc latency cause of the audio skipping and popping sometimes while gaming or browsing the web.

Should you have any questions please ask us. Please read this wiki to find out how to find and upload your event viewer logs. Did both they found nothing wrong. In reply to deleted message. Hello, Thank you for your response. I appreciate your patience and concern. I hope this information helps. Thank you. Here's what really worked for me!! A subscription to make the most of your time.

And how many services are running after boot up is completed but before you run any applications; how much RAM is being used?

If there are a lot of processes listed more than 25 or 30 might be considered a lot -- but I've seen brand new machines so loaded with crapware from big vendors like Sony, HP, Dell, etc, that they had 70 or 80 services running after booting up and RAM usage was over MB just sitting there waiting to get started! I can't remember how many services a fresh install will have running, but my guess is around Ditto the Startup tab. All the crapware like qttask some absolutely unnecessary QuickTime 'helper' app , jusched the bloated and idiotic Sun Java updater, which can take as much as MB just sitting there waiting for a Java update that might come next year , etc -- I just uncheck 'em all, unless it's something I know should be running from startup.

And, guess what, on my machine, that's none of them. Well, except maybe ctfmon, which always just turns itself back on, anyhow. I wish I knew which specific components dell may have skimped on to cause this latency. Some people don't have to disable anything and their latency is picture perfect.

Some machines and BIOS are simply not made for streaming audio. Someone should design an audio and measurement oriented laptop no movable parts ie. I'm so fed with Win XP but I'm not sure the Mac route is the solution either, seems like people experience almsot as much problems on Mac's. A specialty built PC running Linux is tempting but then you run into problems finding software and drivers for some hardware.

All this crap should be a thing of the past really I don't mean to be insulting, but how does memory have direct effect on DPC Latency? No one has defined DPC Latency for me yet. When the device or cpu do not respond, DPC latency spikes occur. Yea, I know the bastard children known as jusched and qtask. When I'm running DPC latency checker, only background process show.

Currently I'm running Windows 7 and don 't feel like reformatting again as the latency is similar to XP. First, programs being opened usually doesnt mean anything--its a component.

Its just confusing you because it has nothing to do with any processes running. I know very little about its fine details and have fixed this problem more than once. I know how you feel man.. Laptops are riddled with DPC problems to the point where many honest manufacturers will warn against using them It is usually the USB or the network card or chip looking for access.

The spikes are caused by terrible designs, errors in hardware or software controlling the hardware, or just a plain disregard for audio I have found that 3 is the most common. They just dont have enough DAW users to justify fixing these things. One things many new DAW users dont understand is there are only a few machines that actually work flawlessly with audio.

The Intel P5k, P35, and P5b being a few of them. These motherboard chipsets take audio into account or just got lucky.

Boot up with the generic VGA driver and test--or stick in an old video card This is how to find the problem djgizmoby disabling and removing each one by one. It can even be a wireless keyboard. If its your mother boards chip set you probably screwed but you can try disabling each USB hub etc in your operating system but search your chipset on the web under audio pops and crackles and you will quickly find out if its a big offenderthe bad news is most chipsets except a few are going to cause some type of problem If you know any daw builder they know this topic like the back of their hands--they know what to use and the boatload of components to avoid.

My Studio. In Windows 7 64 it's about I downloaded the latency checker and it checked all the latencies which are most definitely there for the checking. Now I'm looking for a solution. I'm reasonably sure that the issue I'm having is with my wireless card, but I want to be sure before taking any action, so I tried downloading that process monitor in StereoPari's post.

Could someone please tell me what I should be looking for with the process monitor? There's a filter on it but I don't really know what I should be filtering and what is useful information. I noticed my DPC latency was spiking to around microseconds on mouse usage. Normal idle being around 10 microseconds with all non-essential stuff shut down. Jacking the mouse directly into a USB port instead of into the USB hub cut those spikes down to 50 microseconds, much better.

Might be worth checking that out if you are having DPC latency problems. Good advice. After disabling what I don't need it's never let me down. Quality and priority for audio definitely differs from manufacturer to manufacturer but it's entirely possible to get a great audio machine without much tweaking.
