I have been waiting for serial hours . And finally it was done.

And I am glad to see the that the boot up time is much more faster than before . But the build time is still too long. Is that a way to solve it?

Did you try compiling a starter app? It looks like you have some custom plugins inside your project. Would be interesting if its slow without any customization aswell. Also check your firewall/antivirus system, that they are not blocking and maybe run on Admin context.
