I am facing an issue related to low Transmit performance on PCIE WLAN driver for 11 ac device on a modern standby capable laptop with intel i core 3 and 8 GB ram.
issue is that the transmit performance is degraded by almost 20 pcnt ..after analysis with xperf -on power traces
it is observed that the processor is in c3 state bulk of the time ... as a result it increases the time between the interrupt raised and received by driver.
if i open any application then the throughput increases ..and its observed that during this time the processor is in C1
so it seems if just the WLAN traffic is ongoing the processor is in c3 state most of the time
is there any way from driver i can stop the c3 transition or is there any suggestion to better schedule threads or DPC to avoid c state delay?
thanks in advance
