I upgraded to jdk 7u10 - no noticeable improvement in performance.

Maybe use the very latest version of JDK 7, which I think is JDK 7

I did some searching yesterday and did not find any bug reports. The
places where I really notice a slowdown:
1) Hints pop up (Alt + space) may take a second or more, where under
Java 6 they were quite rapid.
2) In the GUI builder, dragging the edge of a component to change the
size, the dragging is jerky. It used to be very smooth.
3) Some builds take drastically longer than before. I have one
project that for some reason needs Clean & Build frequently. It used
to take right around 60 seconds, now it takes almost twice that.
Granted, I have switched all my projects to "Source/Binary Format" JDK
7, so the compiler might have more to do, but twice as long seems too
I have 8 i7 cores @ 1.73Ghz and 16G RAM, allocated 2G to NetBeans.
I'll wait until Monday, to see if we get any more ideas from the
mailing list and then enter a bug report unless you beat me to it. It
will probably carry more weight if we use the same bug report.

I am not sure. I seem to have roughly the same setup as you OS NB and

Mostly maven projects.
I think it may help us to talk about what we mean by sluggish and be
more clear. I need to find time to study and write up my issues I
noticed with 7.2.1 and Java 7.
Off the top of my head I feel the IDE is sluggish when:
1) I use CTRL+TAB to switch windows. Used to not be this way. The new
window with things other than the editor I attribute to this without
more proof. I often have to wait 2 seconds or the editor tab change nor
dialog with files to choose from will happen/appear. This used to be
extremely fast. Not sure the exact cause though.
2) Often the hints are refreshing or indexes are building and ALT+ENTER
takes forever to show the hints or for the hint symbol to appear so I
can used the key combo.
3) Sometimes rolling over the menus in the window... File, Edit, Tools,
etc can take longer to appear.
I have not yet looked for filed bugs or filed any, but do need to find
the time. I feel some of this is 7.2+ as I was using Java 7 to run
before. Are any of those issues the same as yours? If you file issues or
find them please share the links. I will try to find time to do the
same. Were these issues addressed I think NB would be near perfect on
this machine less a few bugs I have filed in various features...some of
which I know are now fixed in 7.3.

Sorry, I wasn't quite clear. I realize that the 1.6 compiler should
not be able to produce 1.7 files. I was asking if anyone had seen a
bug report on the sluggishness of NetBeans running under 1.7.

This is not a bug.
Source format is not regressible: 1.6 has not necessary
compile 1.7 format.

I recently switched NetBeans to run under the Oracle
Configured this way, NB is noticeably slower,

GUI designer, for example changing the size of a
component, and in
the pop-up code completion hints.
Has anyone else experienced this or know of a fix?
