jp-babel slow on first eval after kernel start about jp-babel HOT 3 CLOSED

I started to notice a slowdown after I upgraded jp-babel to use Babel v6,
but not as as slow as 10-15 seconds. I was hoping using babel-node will
solve this issue. In the meantime, I would recommend to use [email protected]
that depends on Babel v5:

sudo npm install -g [email protected]

from jp-babel.

@gnl Is this still as bad as 10-15 seconds for you?

I'm using:

$ npm install -g jp-babel
/home/user/bin/jp-babel -> /home/user/lib/node_modules/jp-babel/bin/jp-babel.js
/home/user/lib
└─┬ [email protected] 
  ├─┬ [email protected]

    ├── [email protected] 
    ├── [email protected] 
    └─┬ [email protected]
      └── [email protected] 

and I notice a delay of a few seconds only.

I could reproduce this issue on a machine using npm 2.

Using npm dedupe or npm 3, as suggested here, helped me reduce the time to initialise babel to a few seconds.
