Start system_server before class preloading
<p>I was wondering what will happen if the system_server is started in parallel to class preloading in zygote?</p>

<p>I experimented with that a bit but didn't see any problem with activities getting slow. 
There is a good reason for that but I don't know why this is happening.</p>

<p>Can anyone share some info?</p>

<p>Any help is appreciated. </p>
