RE: Java SE 6 - Only Server VM?



Just for the record, it was just a curiosity, not a complaint. I am so far
happy with the performance.  Though I give a +1 to PPC and 32-bit Intel
support... Sun DOES have a 32-bit VM after all, and you already have a PPC
JVM. Presumably the changes in 32-bit Hotspot from Java 5 to Java 6 are not
so huge that the port was out of the question?

I'm not in front of a Mac now so I can't check.  Have you done the same
tweak to the thresholds that was done to "simulate" a server VM in the
earlier releases?  E.g. -client runs the server VM but lowers the compile
threshold to something less server-like?

Regards,

Scott

The 64-bit VM is server only. There is no 64-bit client VM. Sun hasn't  
had one (yet) and thus we haven't shipped one.

If you're referring to Java API features, you get them irrespective of  
the VM. As far as speed is concerned, the 64-bit VM should, in  
general, be faster than the the 32-bit client VM. Others in this  
thread have noted improved Netbeans performance. Try your favourite  
app and see how it does.
