Jato - an open source JVM aiming at better performance

Jato is an open source JVM developed by Pekka Enberg, Tomek Grabiec Arthur Huillet and Eduard-Gabriel Munteanu. That aims at better performance especially at start time

Early versions of Jato are available in 32-bit x86 versions of Linux (the processor will handle SSE2). Unlike the (hot)spot compiling of the Sun jvm, Jato provides compilation on the fly ( just-in-time ) for the whole of the code. This provides good performance even at lauch of the Java application. Although cited ad a boost for desktop applications it will also be useful for cloud computing where nodes are started on demand.

The project also has the aim to optimize the Java application using the performance counters built into the Linux kernel. It is great to see this level of innovation in the JVM.
