Comment 3 Matthias Runge 2016-06-23 15:53:10 UTC
Console is handled by novnc, Horizon just forwards the connection.

Please report the version of novnc being used.

Comment 4 Ondrej 2016-06-24 07:09:03 UTC
Hi,
the issue is hits in both versions:
OSP7:
openstack-nova-novncproxy-2015.1.3-7.el7ost.noarch
OSP8:
openstack-nova-novncproxy-12.0.2-5.el7ost.noarch

Comment 5 Ondrej 2016-06-30 09:05:34 UTC
Chrome works fine up till version google-chrome-stable-50.0.2661.102-1.x86_64.rpm,
once upgraded to version google-chrome-stable-51.0.2704.63-1.x86_64.rpm vnc console began to respond slowly.

slowed: opera-stable_38.0.2220.29_amd64.rpm

Comment 9 Robin Cernin 2016-07-04 10:51:09 UTC
I am running some tests with latest noVNC on Red Hat OpenStack Platform and can confirm that the issue is affecting noVNC. After swapping the noVNC files shipped with upstream code we couldn't reproduce the issue. We need to identify which patch fixes the Google Chrome slowness and backport it.

Comment 10 Matthias Runge 2016-07-04 10:56:11 UTC
Seconded. That's what I found. I even identified a patch, but there was so much refactoring, that I don't believe it's worth the effort to backport rather than to rebase to a later version.

See: https://github.com/kanaka/noVNC/releases/tag/v0.6.0
