For a while Phusion offered Ruby Enterprise Edition[1] which made improvements on the Ruby 1.8.7 interpreter including improvements such as:
> * A “copy-on-write friendly” garbage collector, capable of reducing Ruby on Rails applications’ memory usage by 33% on average.
> * The tcmalloc memory allocator, which lowers overall memory usage and boosts memory allocation speed.
> * The ability to performance tune the garbage collector.
> * The MBARI patch set, for improved garbage collection efficiency.
> * Various analysis and debugging features.
They've since dropped support of it because:
> * A copy-on-write patch has recently been checked into Ruby 2.0.
> * Many of the patches in Ruby Enterprise Edition are simply not necessary in 1.9.
So it sounds like many of the improvements offered in Ruby Enterprise Edition 1.8.7 have been rolled into Ruby 2.0. Do you have any suggestions of what might be included in a Ruby Enterprise Edition 2.0?
There will be no Ruby Enterprise Edition 2.0. REE has been discontinued.
The original goal of REE was to incorporate our copy-on-write friendliness patches into Ruby, and to distribute it in a user-friendly form. Since then, its goal has been extended to include other useful patches as well. We've discontinued Ruby Enterprise Edition for the following reasons:
1. Ruby 2.0 incorporates (or obsoletes) all these improvements.
2. Ruby 1.8 is no longer supported even by its upstream authors.
3. We have limited resources and wanted to focus on Phusion Passenger. Since the discontinuation of REE we've made tremendous improvements in Passenger.
