Front page taking 10% CPU on Safari [moved]

[danielmewes]

Moved from rethinkdb/docs#714, reported by @larkost :

Just having a Safari window open to the rethinkdb.com front page puts a 10% CPU load on my machine. We probably should not be using that much. Other pages don't seem to use that much.

[danielmewes]

Didn't we have some issue with constant flickering on Safari? Could that be related?

Chrome on my machine takes between 30% and 40% when the graph or changefeed emulation is in view respectively and I agree this is far too much.

[danielmewes]

Yeah I retract that comment. I can reproduce it with Firefox as well, 20-30% of one core.

[larkost]

The flickering was on an iPhone 6+, but the underlying issue is one with REM in stylesheets and should not be the issue here.

The issue here is the JavaScript that's running the animations on the front page. The animated line graph on the image of the dashboard by "Scale your cluster in seconds" may be the chief culprit; if I comment out the transition so the lines aren't being scrolled with perfect smoothness, CPU usage drops noticeably.

@danielmewes As the opener of this issue, are you still getting this?
