    Question LatencyMon: high "Highest measured interrupt to process latency" without high ISR or DPC numbers ?

    Thanks very much for the follow-up. I have an SSD and have never seen storport.sys come up in LatencyMon except for this one occurrence. I'm still seeing some results where "Highest measure interrupt to process latency" is the only real problem, by the way, but other times a driver will also...

    Question LatencyMon: high "Highest measured interrupt to process latency" without high ISR or DPC numbers ?

    Hi again. I wanted to spend a couple of days testing and ended up having problems on two consecutive days and disabled both hyperthreading and C states in BIOS in between. The LatencyMon reports differ between days, but the PC is still having intermittent (though almost daily) DPC latency issues...

    Question LatencyMon: high "Highest measured interrupt to process latency" without high ISR or DPC numbers ?

    Thanks for the advice. I'm new to the forum and couldn't easily find a way to upload a screenshot (aside from posting it somewhere where I can copy the URL here). REAPER is a DAW (digital audio workstation): https://www.reaper.fm/ I appreciate the suggestion for checking the drivers and...

    Question LatencyMon: high "Highest measured interrupt to process latency" without high ISR or DPC numbers ?

    Thanks a lot for the additional feedback. Apologies for not being sufficiently clear, but the internal Wi-Fi of the PC is unused and the 100 Mpbs Ethernet port is hardwired to the external Wi-Fi extender in question. As such, the Ethernet port is the only network port that's actually in use. I...

    Question LatencyMon: high "Highest measured interrupt to process latency" without high ISR or DPC numbers ?

    Thanks for asking. It's actually a Wi-Fi extender that connects to the PC over wired 100 Mpbs Ethernet. As the PC doesn't directly interface with this extender (and I still have these intermittent problems when the wireless extender is unplugged from its power source), I don't think it's likely...

    Question LatencyMon: high "Highest measured interrupt to process latency" without high ISR or DPC numbers ?

    Thanks for your kind reply. I'll run LatencyMon again and will investigate the Drivers time the next time around. I usually keep this PC offline while recording, but it is normally connected to an external Wi-Fi adapter at all other times (as was the case yesterday). I don't use the internal...

    Question LatencyMon: high "Highest measured interrupt to process latency" without high ISR or DPC numbers ?

    Hi. I have a Dell Precision 3420 SFF Intel i7 Desktop PC on which I'm running REAPER and have been experiencing intermittent brief audio dropouts. Some days I can spend an hour or two without any problems but the problem will show up one or more times on other days. After performing a complete...
