Subject: Requesting support for CPU performance and benchmarking in the
 presence of network

Hi,

We have a test bed DUT with OpenWRT While Capturing CPU usage, we
observed below points.

1. 5 mobile clients are connected to the DUT and streaming HD video
consumes CPU usage 0 to 5%

2. 5 mobile clients are connected to DUT and streaming HD video and
downloading a 350MB file for every 3minutes then CPU usage is 8% to
30%

If I increase the number of downloads then softirq increased and CPU
usage has reached to more the 30%

Will we have any impact on CPU if softirq's increases?

Please help me to confirm, is this an issue? are we need to consider this issue?

Thanks in advance.
