Capybara Webkit very slow?

[David Kennedy]

I'm using RSpec with Capybara Webkit, but I'm seeing veeeery slow
tests, with an average of 12 seconds for a single test! From my
reading, this is much slower than should be expected. Debugging /
profiling this is very frustrating, does anyone have any advice? Is
this a known issue?

This is on an Ubuntu machine, and I wonder if it's related to

Maybe you could check external resources on your pages (e.g. extremely slow advertising, for example).

I am also seeing slowness on Ubuntu. I have a test that does hundreds of page.find and element.text calls on a very large page. The test takes about 45 seconds on my MacBook Pro, but close to 15 minutes on a very fast Ubuntu machine.

No external resources are being loaded on the page. I have not spent much time investigating it yet, but it looks like finding elements on a large page is very slow on Ubuntu.

I was able to speed things up a bit by explicitly setting:

Capybara.automatic_reload = false

Same problem on my Ubuntu machine.

I noticed that the webkit_server process seems to be sleeping most of
the time while running the features.

On my Intel I3 this process averages around 5% CPU in top.

So either something inside this process is blocking, or it doesn't
receive work fast enough.

Maybe this helps a bit.

Cheers,
Marc

I am experiencing a similar problem on Windows:

Visiting a page (one step):

    user     system      total        real
1.719000   2.688000   4.407000 ( 44.955124)

Hello, did you solved this problem? I have the same on my Ubuntu machine, but on Mac it runs 3 times faster...

Any decisions guys? For me it 50% slower on Ubuntu than on Mac OS.
