How could I reduce the Hybris server startup time?
I am working on a Hybris project and it is very time consuming to wait 350 - 550 sec for a single Hybris server startup, for even just a little modification/misstype in the code. Is it possible to reduce this time by running only those extensions I have modified or any other way? That would be a great thing.

+1 on JRebel. It works well with hybris. Sure, it's expensive, but you'll rapidly get the ROI savings. The initial load is slower, but once it's up it'll save a lot of time.
The other thing to do is to take a look at your localextensions.xml and ensure only the extensions you need for your project are in there. It makes a big difference to the start up time.
I've also seen reasonable start up time improvements through using a DB other than HSQL when running the platform. I use MySQL locally.
The other thing is to ensure you've got enough grunt in the machine you're using. I've just started the platform here and even with JRebel running it's 'only' taken 200 seconds. I'd suggest looking at a quad core CPU and an SSD to improve times for local development.
