<p>Like I said...you won't know unless you test it in your situation.</p>
<p> </p>
<p>Generally speaking.</p>
<p>#1 Any added layer slows things down. But it may not have much of an effect it that's only a small part of the processing.</p>
<p>#2 I would suspect packet loss to NOT occur until CPU usage hits 100%. But I wouldn't trust that statement without testing it.</p>
<p> </p>
<p>So...to emphasize...YOU DON"T KNOW UNTIL YOU TEST IT YOURSELF IN YOUR SPECIFIC SETUP.</p>
<p>On the other hand, even with testing, you can't make the statement that you can guaratee capturing 100% of the traffic as you have no way of proving that. You can state such with "high confidence" after you test, like this "testing shows CPU usage at X%
and no packet loss has been seen from our testing".</p>
<p> </p>
<p>I take it you're plugged into a hub and not a switch or into a monitoring port set up on a switch? Otherwise you won't see anything but your own traffic.</p>

<div>Ty so much for your answers. So there wont be any packet loss unless cpu usage is under %100 and using a wrapper will not affect the performance.
