Do you know that most of the web sites, services and whatever on the internet are powered by Java and by a good percentage by Tomcat? Java = slow is bullishit at least since five years, so please don't spread FUD any longer. > Yes, the java JVM works nicely in a server environment. Again, for > your standard server applications. Subtle things in the GC process > (as previously explained) make it too slow optimal performance. Other FUD. GC is no more a problem, unless a programmer is really ham-handed, since several years.

There are plenty of benchmarks around that demonstrates than Java or C are faster. The JIT technology, BTW, allows for higher optimization than C, since it can only optimize statically. Of course, single benchmarks aren't meaningful, since in a real world project one have to do some trade-offs. There are many real-world examples that can be done, just the first one that is public and comes to my mind has been recently presented at Jazoon. See http://jazoon.com/Conference/Thursday/OMullane, slide #40, which I'm copying: Is Java fast enough.. ? On some processors with highly tuned C compilers the C can be faster than java (max factor 2) ?You can play cat and mouse for ever with any specific piece of code .. ? On most Intel?s Java is as fast or faster than C ?JIT(JustIn Time) Compiler with Hotspot remarkable! ? Just one example from Gaia ?Relativity C code running in simulator 10 years on super computer ?The orginal Author rewrote it in java ?Its is ~10 times faster in JAVA ! - -- Fabrizio Giudici - Java Architect, Project Manager Tidalwave s.a.s. - "We make Java work.
