Foil 50 What Limits Performance of Compiled Java?

From The Use of Web Technologies (at NPAC) in HPCC Collaboration and Education Trip to Digital Corporation in New Hampshire -- May 8 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
