Foil 30 What Limits Performance of Compiled Java?

From The National/Next Generation Information Infrastructure in the service of Education Training and Computational Science RCI Federal SIG Meeting Williamsburg Marriot -- April 17 97. by Geoffrey C. Fox *
Syracuse Workshop saw no serious problem to High Performance Java on sequential or Shared Memory Machines
Some restrictions are needed in programming model
For instance, Avoid Complicated Exception handlers in areas compilers need to optimize!
Should be able to get comparable performance on compiled Java C and Fortran starting with either Java Language or JavaVM bytecodes
The Interpreted (Applet) JavaVM mode would always be slower than compiled Java/C/Fortran -- perhaps by a factor of two with best technology
