<div class="moz-cite-prefix">hi, <br>
just to make sure did you disable the debugging and verbose in
nova, keystone and horizon ? I had this enabled and it was very
slow... <br>
<br>
Hope this help.<br>

<div>Hi All,<br>
<br>
</div>
I have a single controller node 60 compute node cloud on
Ubuntu 12.04 / cloud archive and after upgrade to
grizzly everything seem painfully slow.<br>
<br>
</div>
I've had 'nova list' take on the order of one minute to
return (there's 65 non-deleted instances and a total of
just under 500k instances in the instances table but that
was true before upgrade as well)<br>
<br>
</div>
The controller node is 4x busier with this tiny load of a
single user and a few VMs as it has averaged in production
with 1,500 VMs dozens of users and VMs starting every 6sec
on average. <br>
<br>
This has me a little worried but the system is so over
spec'ed that I can't see it as my current problem as the
previous average was 5% CPU utilization so now I'm only at
20%. All the databases fit comfortably in memory with
plenty of room for caching so my disk I/0 is virtually
nothing.<br>
<br>
</div>
Not quite sure where to start. I'd like to blame conductor
for serializing database access, but I really hope any service
could handle at least one rack of servers before you needed to
scale out...but besides the poor user experience of sluggish
response I'm also getting timeouts if I try and start some
number of 10's of servers, the usual work flow around here
often involves 100's.<br>
<br>
</div>
<div>Anyone had similar problems and/or have suggestions of
where else to look for bottle necks.<br>
