Despite the stereotype, Java actually performs quite well, and is used 
in highly concurrent, real-time environments like telephony extensively. 
  I think the stereotype about slow interpreted languages belongs to the 
first era of Java (1996-2000(?)), back when it had green threads and so on.

Having said that, it is true that the JVM consumes a lot of resources 
just to run at all, and that the bureaucratic fashions of Java are 
chiefly an affectation of the enterprise world.  However, once it spools 
up and gets going, Java is quite fast, and adequate for SIP.  It has 
posted comparable benchmarks to C for many scientific computing 
applications for years now.

Initially, I was as surprised by this as you are.
