Build takes very long time after seed upgrade

[Toktik]

After upgrading angular2-seed for my project, I get very slow npm install and builds.

[06:36:46] Requiring external module ts-node/register
[06:37:23] Loading tasks folder C:\project\client\tools\tasks\seed

It takes around 40 seconds between those steps if you look at the time diff.

It fixes when I downgrade ts-node dependency from 0.7.1 to 0.5.5.

I don't see anything suspicious in my setup.
Either it is ts-node itself or the way we use it. Any idea?

It could be ts-node. At this point we don't want to give up static typing so there is nothing much that we can do.

Here's proposal for ts-node 1.0 which will bring a lot of performance improvements TypeStrong/ts-node#44.
