Thanks, I would expect it to be about half, the code for `extend` is pretty slow.

@phpquery Would you mind testing out the latest code in the 1.6 branch? On my system, bootstrap 3.1 is taking about 5.5 seconds with the new code

Sorry, it's not tagged yet, it's just the [current 1.6 branch](https://github.com/oyejorge/less.php/tree/1.6). Here's the [1.6 branch download](https://github.com/oyejorge/less.php/archive/1.6.zip) if it helps

I wouldn't say I've stopped working on performance. I think there's room for more improvements, but I've hit a wall so I'm going to take a little break and come...

That's perfect, thank you. I get the feeling those results are actually more accurate than what I'm getting with xdebug.

Just to throw this out there, I just added [hhvm](https://github.com/facebook/hhvm/wiki) to the travis.yml to see (1) if the tests would pass and (2) what kind of performance improvements we'd see....

Not that I know of. I'm just looking at the time it takes travis-ci to complete the tests. Note: I'm not looking at the "Duration" time at the top of...

I know comparing run times of different php versions on travis-ci isn't the best way to judge performance but: php 5.6 > Time: 12.13 seconds, Memory: 40.75Mb php7 > Time:...

Doesn't look like less.js has gone for the dual license yet. I'm happy to change less.php to whatever they decide to go with. Here's the relevant less.js issue: https://github.com/less/less.js/issues/1029
