The table below provides a comparison of various virtual machines

Feature	HLVM	Parrot	Mono (CLR)	JVM
Language Support	None, yet, but designed to targets any language; focusing first on dynamic languages like Python and Ruby	Perl mainly, possibly Python and Tcl in the future.	C# mainly, but other languages possible	Java almost exclusively: very hard to use JVM for other languages
Execution Models	HLVM will be able to execute a program in any of the following models: Interpretation of AST quickly compiled from source (coming). JIT compilation from bytecode (already implemented by LLVM). Native, optimized, binary execution (works now).	TBD	TBD	TBD
Optimization	Offers a wide range of optimization levels from "none" to "life long". Most of this is provided by LLVM and works today. LLVM is "state of the art" for optimizing compilers. The amount of optimization applied can be specified by the user or inferred from the program's usage and workload.	TBD	TBD	TBD
Language Interoperability	AST	PIR	IL	JVM Bytecode
License	LGPL	?	Mono:? CLR:Proprietary	?
