I'm not sure why, but this was being caused by the bootstrap-style progress bars left over from when the page was originally contributed to us. I replaced them with observium-style percentage bars and the issue went away.

Chrome's debugging tools might help.

That's probably one of the simplest pages we have, though.

I see ~10% CPU load on this page. It seems to be repeatedly repainting the page after a style recalculation, and I have no idea why.

If anyone understands how to work out what's happening, please have a look at Chrome's debugger.

Well… I was simply asking if anyone had the same experience (on the version we were on…) Anyway… went to 8249, should be current stable, same issue.

IE:

/overview/ - CPU at 0%

/pollerlog/ - CPU up to 46 – 48%

…and back to /overview/ - CPU back to 0%

 

Chrome:

/overview/ - CPU at 0%

/pollerlog/ - CPU up to 33 - 36%

…and back to /overview/ - CPU back to 0%

 

Haven’t seen this behavior on any other pages. Strange.

This sounds unlikely. There's nothing dynamic on that page, just a couple of graphs and a lot of text.

 

Also, why are you trying to report issues for an old version?

Hi

 

We’re experiencing high CPU-load for the browser-process when having the /pollerlog-page open.

In IE there is a +45% raise and in Chrome (54) a +30% raise.

We’re running 8086. Is anyone else experiencing the same issue? Bug?

 

Regards,

Tobias
