yargalot/grunt-accessibility#31 as per @XhmikosR's, previous issue

[XhmikosR]

@yargalot: I notice the slowdown mostly happens on Windows.

Can you set up AppVeyor for this repo to see the slowdown yourself?

Example:

https://travis-ci.org/mpc-hc/mpc-hc.org/builds/171916862
https://ci.appveyor.com/project/XhmikosR/mpc-hc-org/build/691

Windows: accessibility:test 1m 14.9s
Linux: accessibility:test 6.4s

@XhmikosR that makes sense, I've added it in over at https://ci.appveyor.com/project/yargalot/accesssniff

Im going to put in some benchmark tests and see whats going on. Also going to try it out using JSDom instead of phantomJS and see if that speeds things up.

[yargalot]

jsdom is a ton faster

[yargalot]

Phantomjs x 0.24 ops/sec ±0.36% (6 runs sampled)
JSDom x 35.13 ops/sec ±9.06% (61 runs sampled)
Slowest is Phantomjs
Fastest is JSDom

[yargalot]

Done in 3.0

@XhmikosR can you give the 5.0 grunt accessibility update a shot and see how it is?

[XhmikosR]

@yargalot: now it's consistently a lot more slower both on Linux and Windows :/

[yargalot]

Hrmmm, l've got your repo on the laptop. Ill run some benchmarks tonight and see whats up

[yargalot]

@XhmikosR Can you set the browser to true in options and see if its any quicker?

[XhmikosR]

@yargalot: with browser:true it's as fast as it was with v4.x.

Still Windows is a lot slower.
