Hi Andy and Michael,<div><br></div><div><br></div><div>We need to enable CTS tests for few of the builds as they are a requirement for few projects. Is there anyone looking at the issue from the lava-dispatcher end since load could be an issue once we enable back CTS.</div>

<div>For now I tried two ways to verify it:</div>
<div>1. Run the CTS test via submitting a lava-job</div><div>    In this way, the process that consumes CPU is telnet</div><div>2. Run the CTS test via command line &quot;lava-android-test run cts&quot;</div><div>    In this way, there is no process that consumes CPU to 100%,</div>

<div>    In the meanwhile, I also opened the telnet session.</div><div><br></div><div>So I guess the problem is the way we calling the telnet command in lava-dispatcher.</div><div>From my investigation, it&#39;s the select syscall in telnet that consumes CPU,</div>

<div>So I doubt if there is some place in lava-dispatcher that reads the ouput of telnet in a loop without sleep in the loop.</div><div>but I did not find such place in lava-dispatcher.</div><div><br></div><div>How do you think about it?</div>

<div><br></div><div>Finally, I feel that this problem is of lava-dispatcher, not the problem of lava-android-test or CTS,</div><div>so can we change it to be a bug of lava-dispatcher?</div><span class="HOEnZb"><font color="#888888"><div>
