reduce roscore startup time

Hello,

I'm running ros on an embedded system (2xCortexA9@900MHz). It takes about 13 seconds till roscore is ready. The problem is, that I need a running system with roscore and some small nodes after about 12 seconds. The bootup time of the operating system (~3sec) is included, so roscore must be started in 9 sec. or better.

I used the python cProfile module and runsnake but I didn't find the "one" time consuming element. Are there any ideas how to reduce the startup time of roscore? Is it possible to "compile" roscore (binary without python)?

Thx!
