---------------------------------------

Yeah, but the size might be the culprit. Typically platform repo has its dev 
dependencies installed, which increases size of {{node_modules}} dramatically 
(in fact, from 4 to 50 megabytes, see attached screenshots). For me after doing 
{{git clean -xdf}} in platform repo it takes even less time to install from 
local folder rather than from NPM. Below are my timings:
{noformat}
// on a fully installed repo, after npm install
➜  baz time cordova platform add ../cordova/cordova-ios
cordova platform add ../cordova/cordova-ios  3.94s user 2.66s system 105% cpu 
6.237 total

// after doing git clean -xdf, only production dependencies installed
➜  baz time cordova platform add ../cordova/cordova-ios
cordova platform add ../cordova/cordova-ios  1.85s user 0.39s system 116% cpu 
1.922 total

// from NPM
➜  baz time cordova platform add ios
cordova platform add ios  3.11s user 0.74s system 109% cpu 3.524 total
{noformat}

> On my system, when installing a platform from a local path, it took 43s.
> Adding the ios platform from npm took 12s. A 3.6x slowdown.
> Investigate where the bottleneck is.
> {code}
> cordova create t t t
> cd t
> cordova platform add path/to/local/platform-ios
> {code}
> Using the --verbose flag, the step that takes the longest time is at:
> "Copying iOS template project to /Users/shaz/Desktop/t/platforms/ios"
