Hi all,
Since I upgraded engine to 3.6, I noticed that the webadmin takes a lot
of ressources whatever is the browser. It can become very slow even for
small actions, like changing tabs or editing a vm. The browser activity
becomes intensive (100% of cpu) and the processor very hot with a
increased fan activity. I suppose javascript to be responsible of this
behaviour. Is there a way to reduce the resource allocated to the webadmin?
(This is not a weakness of my laptop which is an i7 cpu with 16GB of RAM)

Sounds like https://bugzilla.redhat.com/1264809
It was closed because we could not reproduce it with current versions.
I would try first to upgrade to latest 3.6 version, and if you can reproduce it,
please reopen this bug.
Alexander: can you advice on how to debug this?

If you are willing to spend some time helping us debug that would be great as
obviously we are unable to reproduce. If you have Chrome, can you open the
development tools (ctrl-shift-i) and go to the 'Profiles' tab. That should give
you the option to 'Collect Javascript CPU Profile' among other things. Make
sure you select that, and click start. Then go in the web admin and do
something that makes your CPU spike. Let it go for a little bit doesn't have
to be long.
Go back to the CPU profiles tab and click stop. That will generate a profile and
that profile will include the percentage of CPU usage per method. It should be
sorted by percentage. If you can take a screen shot of that and give me the
exact rpm version, I can use that to de-obfuscate the method name and
hopefully get some useful information.
Thanks,
Alexander

You can also save such profile to file, and attach it to the bug.
When I reorted this, this was also reproducible in Firefox, and both profiles
are attached to the bug.

We have patches in review that should fix this in 3.6.5. The underlying
problem is a couple of JavaScript memory leaks.

Yeah, sorry everyone. There's actually evidence that this leak goes back to
3.5. It's a nasty one.
The major memory leak is in the footer, which updates every 5 seconds by
default. Changing the refresh setting to 60 slows down the leak. But
depending on your setup, ymmv. There's also a smaller leak in bootstrap's
tooltips which hit us pretty bad, for which I've submitted a PR [
https://github.com/twbs/bootstrap/pull/19659 ]
Best wishes,
Greg

Since 3.6.2 or 3.6.3, the web admin is getting close to unusable

Thank you.
Thank you also. I'm on 3.6.4 just released version and it can take 5+
minutes to go from the welcome page to the admin login page and then
the interface is slow and frequently throws exceptions.

Thank you also. I'm on 3.6.4 just released version and it can take 5+
minutes to go from the welcome page to the admin login page and then
the interface is slow and frequently throws exceptions.
Two things to check if going from the welcome page to the login page is THAT
show.
1. Make 100% sure your DNS is setup correctly (or your /etc/hosts if that is
what you use). If the engine cannot resolve itself, it will create lots of
issues.
2. If you are running hosted engine, make sure you have enough entropy, the
login page generates a couple of tokens using secure random, which eats away
at your entropy budget heavily and since hosted engine is a VM it is possible
that you don't have enough entropy. You can check your entropy level with
this:
cat /proc/sys/kernel/random/entropy_avail
There are several options for solving the entropy problem if that is the case.

Hi everyone,
If you've experienced this issue and you're able to upgrade to 3.6.5, I'd
love to get your feedback on the responsiveness of the webadmin UI now.
