Even on my SSD (and travis uses SSD as well) zipping is a very slow process (on my fast machine)

Some ideas would be to use less compression https://github.com/mozilla-b2g/gaia/blob/master/build/webapp-zip.js#L35. Using none http://mxr.mozilla.org/mozilla-central/source/modules/libjar/zipwriter/public/nsIZipWriter.idl#40 seems to yield better results:

I don't believe the level of compression is important for tests (but using packaged apps are!).
