Re: [cross-project-issues-dev] Performance, 3.8 versus 4.2



You are certainly not the only one seeing performance issues with 4.2. I go back and forth between 4.2 and 3.8 every day depending on the project I need to work on and the difference is quiet noticeable even on very fast hardware. The part I notice the most is the lengthy close all editors process. After drilling down into some task and opening a few dozen editors, clearing workbench of open editors takes several seconds. I can literally watch tabs disappear one by one. The same operation is practically instantaneous on 3.8.


For stability, user experience and performance reasons, you will find that many third party distros have stayed on 3.8 for Juno.


I don’t begrudge 4.x its growing pains. It is a complex technological shift with a lot of promise. What I find most troubling is the decision process that led to the use of 4.2 for Juno distros. When the decision was made, it was plainly evident that 4.2 wasn’t going to match 3.8 on any of the quality metrics. IDE users might have been ok with quality drop if 4.2 delivered compelling new functionality that you couldn’t get in 3.8, yet there is no tangible functional delta. The value of 4.x platform is for RCP developers and to certain limited extent for IDE plugin developers. Certainly not for IDE users. The refreshed look-n-feel has been touted as a big end user feature of 4.2, but the new look-n-feel itself has numerous issues that leave it looking like an unfinished project.


Sadly, the user reaction that we’ve been seeing over the last several months has been entirely predictable.

It's an issue not always reproducable.

I never meet such problem in my environments. But I know somebody has similar problem.

Bug 385272[1] is a known report.

For various reasons I had to switch my development environment from 4.2 to 3.8 today. I was stunned by the performance improvement after the switch. The 3.8 platform is much MUCH faster. It boots faster, it closes windows faster, it shows menus faster, etc. It also seems to consume less memory and be less buggy. The way things stand right now, there's just no way I'll switch back to 4.2!

I must say I was very surprised by this. Why is the 4.2 platform what's being fronted on the Eclipse download page when it's user experience and quality is lagging behind this much? Is it just me who have had this experience?
