[eclipse-dev] Eclipse Platform Juno performance resolution and patch

[John Arthorne <John_Arthorne@xxxxxxxxxx>]

A few months ago there was some discussion
on this list [1] and elsewhere about Platform UI performance problems with
the Juno (June 2012) release.  With some excellent community help
in narrowing down the problems, the project committers have now resolved
the most significant problems that were raised. These fixes will be available
in the Juno Service Release 2 (February 2013), and Kepler (June 2013) releases.


While waiting for these releases, users
of the classic Eclipse SDK who are affected by the performance problems
are encouraged to move up to a recent 4.2 stream maintenance build, available
from the Eclipse project download page [2]. The stable Kepler M4 milestone
build, due to arrive at the end of this week, also contains all of the
performance fixes. If you are using one of the Eclipse Juno SR1 packages,
an official patch is now available that will apply all performance fixes
on top of those packages. While this patch has been well tested, it should
not be treated as a formal release. The patch did not undergo the usual
formalized shutdown process or IP review of a full Eclipse release - it
is essentially a stable maintenance build in a form that is easy to consume
for users of the Juno SR1 packages.

Complete details on how to install the
patch, and background on the details of the performance problems and investigation,
can be found on the following wiki page:

http://wiki.eclipse.org/Platform_UI/Juno_Performance_Investigation

As always if you encounter problems
with the patch, or further performance problems while using these recent
builds, do not hesitate to report new bugs in the Eclipse bugzilla system.
