<div dir="ltr">Cool, thanks, Jon. I've been following the thread on your scheduling issue on the OpenStack list. I can't see our users hitting that issue, but it's always good to keep in mind. :)</div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Feb 17, 2015 at 1:17 PM, Jonathan Proulx <span dir="ltr"><<a href="mailto:jon@jonproulx.com" target="_blank">jon@jonproulx.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Recently (4 weeks?) moved from Icehouse to Juno. It was pretty smooth<br>
(neutron has been much more well behaved though I know that's not<br>
relevant to you).<br>
<br>
One negative difference I noticed, but haven't really dug into yet<br>
since it's not a common pattern here:<br>
<br>
If I schedule >20 instances in one API call I get conductor timeouts<br>
and zero launches. If I make many parallel scheduling calls for <20<br>
instances each response is good and scaling out to several hundred<br>
parallel launches is much faster and with out the neutron timeout<br>
errors that plagued me since I switched over to quantum in Grizzly.<br>
<br>
As I said I've not looked deeply at this so it may be a local config<br>
issue rather than something systemic with Juno, but if it's an<br>
important use case for you be sure to take a good look at it.<br>
