Improve gradle startup time with groovyserv or nailgun or what

Question

I'm trying to improve the startup time of Gradle. The expererimental --daemon switch doesn't seem to really speed it up. So I'm thinking to use some server process independent of gradle, and make gradle connect to it. The options I found so far are

• nailgun to invoke java
• GroovyServ to invoke a groovy script

Since gradle is started by a shell script, it takes some tweaking. My question is: has anyone used the above options to start gradle? Or if you have successfully used another option, what's that?

My guess is that your build is doing something at configuration time that it should be doing at execution time. With m5, gradle build --profile will give you an HMTL report showing where the time goes. Another way to see what's going on is gradle build --info or gradle build --debug.
