So, I have been messing around with trying to address my DPC latency (I've read other replies in this forum as well.) Since I have an idea of many different routes/avenues required to fix this issue, I've gone ahead and tried many. I've done the following:
1) Updated my network card drivers (this seemed to reduce it from averaging 5k Highest reported DPC routine execution time to around 2-3k. Not a major improvement IMHO) This is because ndis.sys seems to usually be the issue (which happens when opening chrome with multiple tabs.)
2) If I disable network card drivers and still open all those tabs, the next culprit (averaging around 450 microseconds in the field where ndis.sys was a problem before is the Nvidia driver file nvlddmkm.sys)
3) I've gone ahead and created the xperf etl file for anyone to use here as I am not quite sure how to interpret it properly after spending about 5 minutes mulling it over:
Google Drive CPU.zip share
Thanks for any assistance in advance!
