Anyone have experience or comments on how stable Version 6 is???

It's very good. It has some nice features but is a bit slow.

Perhaps it's the hardware - there must be a threshold over which NB no longer
seems slow.

I run NB 6 on Fedora 7 with a 2GHz AMD 64b CPU, 32b Java 6u3 from Sun. 1 GB
RAM on the machine, but it's also running Postgres and Apache Tomcat when I'm
developing with NB.

Overall I don't notice the speed of the IDE. I do notice the speed of
compiles and other build-related activity. I notice them when using the
command line, too.

My basis for speed comparison on an editor is emacs. NetBeans' is the much
busier editor - it's always scurrying about making popups on Javadocs, method
completions, annotation suggestions, syntax coloration and validation (using
the new Java compiler-within-a-JVM feature), brace matching, style nagging and
for all I know, starting the coffee maker. I guess it's a wonder the thing
moves at all - but seriously, I never seem to notice NetBeans' speed on any
CPU running at 2GHz or so with a good gigabyte of RAM.

Try tweaking the etc/netbeans.conf settings.

netbeans_default_options="-J-client -J-Xss1m -J-Xms32m -J-XX:PermSize=32m
-J-XX:MaxPermSize 0m -J-Xverify:none -J-Dapple.laf.useScreenMenuBar=true
-J-XX:+CMSClassUnloadingEnabled -J-XX:+UseConcMarkSweepGC
