Huge performance improvement

[sergiou87]

This patch uses the definition cache while the assembly is populating it.

The problem was that in a given assembly you may have two definitions, say A and B, where B depends on A. Instead of processing A definition and then share it with B, it's built twice: one for A definition itself, and another for B definition's dependency.

Therefore, we can see that the Assembly is traversing not only the whole object graph (that's necessary) but also all the subgraphs, building all definitions it finds along the way.

With this patch my app (~400 classes) went from:

• Launch time: 30 seconds
• Initial memory footprint: 90MB

to:

• Launch time: 0.045 seconds (667x faster)
• Initial memory footprint: 15MB (6x lower)

The current performance in the 1.8 version is a HUGE problem for my team to work in our app (long development times, and we cannot deploy in a device because iOS kills the app due to its long launch time).

Is there any possibility to release a 1.8.1 version with this very same patch so that we don't have to point our Podfiles to my fork until this patch is released?

Thank you in advance!

Great work @sergiou87 . . publishing Typhoon 1.8.1

If you have other ideas, @sergiou87, we'd love to hear about them.

I was pleasantly surprised to update my Podfile today. I'm seeing a huge memory improvement as well as noticeably faster launch times.

Thank you @sergiou87.
