Hi David,<br><br>When I was testing 1.6.1 for high volume channels, I couldn't get over 1000 channels / 40 CPS without the load average spiking up due to io wait. I switched back to 1.4 and I can go to 3000 channels / 75 CPS with no io wait and a load average in the 1s. It seemed like it was caused by the new timing system in 1.6.1 even though I wasn't proxying media using only SIP.<br>
<br>I haven't tried 1.8 yet to see if it handles large call volumes any better.<br><br>~Jared<br><br><div class="gmail_quote">On Wed, May 11, 2011 at 8:29 PM, David Cunningham <span dir="ltr"><<a href="mailto:dcunningham@voisonics.com">dcunningham@voisonics.com</a>></span> wrote:<br>

I can't see anything wrong, so is this just expected with 1.6? Can anyone help explain it?<br>
