MyEclipseIDE is a complicate tool, she has many function, but there is not everyone will use every function she has, if there are options that allow disable some function, the performance maybe better.
I support the previous users request for a light weight version or the ability to disable some functionality. Whilst many of the features are great – its getting to the point where the productivity is actually decreasing because of the huge resource requirements. P4 2GH machines with 512MB of memory grind to a halt and the ide can’t even keep up with user typing. The requirement for a light weight version is paramout to our continued use of the product for the team I lead we will have to start looking at alternatives in the next 2 months.

=/, I don’t know about that… you just described my machine and a machine better than 2 of our developers. What are your command line arguments to start Eclipse with? How many plugins do you have listed under Eclipse/plugins? What version of MyEclipse are you using? (this is important).
We are running Eclipse Platform version: 3.0.1 – Build id: 200409161125 and myeclipse version 3.8.3. We have tested various command options, the idea slows down over time and then becomes too slow to type. We don’t get an out of memory or any such errors so that is not the problem. We have even tested tunning gc perfomance with: eclipse.exe -vmargs -Xverify:none -XX:+UseParallelGC -XX:PermSize=20M -XX:MaxNewSize=32M -XX:NewSize=32M -Xmx256m -Xms256m … and a few other options, they help slightly.
We have also tried disabling some plugins at startup etc. Most of my team is still runing version 2, we would love an IDE that just does java and jsp code completion, compilation etc well. We use xdoclet and hibernate but controll these manually via the ant scripts so as reduce the use of plugins as the idea is too slow. Our projects are quite big 3500 jsp, 1000 java classes.
-Xverify:none
Don’t use this argument, there is some problem with this and Eclipse that I’ve seen in the past.
-vmargs -Xverify:none -XX:+UseParallelGC -XX:PermSize=20M -XX:MaxNewSize=32M -XX:NewSize=32M -Xmx256m -Xms256m
I am not currently aware of anyone else encountering performance as poor as you describe such that they need to use flags this aggressive. I tend to avoid using aggressive flags simply because of the side effects that sometimes popup. Can you honestly see a difference between all these flags and simply using -Xmx256m?
Most of my team is still runing version 2
Do they experience the same slow downs as the people using version 3.x?

How many projects of this size do you have open at the same time? This can be part of the problem, I know it will effect debugging as lookup has to consider every open project which would make it abysmally slow.
Please note that I’m not trying to contest your claims, I’m just trying to figure out why it is SO painfully slow for you and your team. Also you didn’t mention how many plugins you have in the Eclipse/plugins directory.
The jvm settings I gave were just samples of things we have tried. I am currently running the default configuration with no tweaking to gc. We did get a few weird problems with cut and past not working in the editor from time to time with the agressive gc options, but there was a noticeable performance improvement initially until things slowed down, stability was also a bit of a problem.
We are runing the stock standard eclipse 3.0 install, I have removed the help modules and ssh cvs to see if that would help. I am running windows Xp professional with service pack 2 and the settings optimized for performance.
Eclipse version 2.1 and the early 3.0 milestones I looked at M7,M8 etc were all much better than 3.0. The latest release is a problem … I tried rolling back, but simply switching does not work so I am assuming I would have to reinstall. I am currently evaluating an upgrade path for the dev team, so I am the only one looking at 3.0.
We generally only open 1 project of that size at a time, we have a few that we are working on (j2ee projects with jsp web interfaces, a few legacy ejbs, hibernate mapped pojos etc – deployed to orion). Jsp typing is a huge problem, I have tried disabling xml validation etc, but it is still slow – you can physically see the underlined warnings for unused imports flashing on a screen repaint.
The performance seems to start out ok and then get slower and slower with 100% CPU utilization until it is not usable and needs to be restarted. The memory available is fine and the machine is not swapping. Maybe it has to do with your indexes on the debug typing geting fragement, I am not sure how this is implemented ?
It would be really great if we could disable more features or have access to more of the underlying settings.
Here is a list of my plugin as per the configuration options.

There is an open enhancement request to be able to turn the ‘reconciler’ off, that is what is causing this.
I am currently running the default configuration with no tweaking to gc.
I would highly suggest: -Xms128m -Xmx256m
That seems to give the best success with the most people. Runnin with -Xmx command is not a good idea as the base heap of 64 will quickly be hit.
We are runing the stock standard eclipse 3.0 install
I would definately encourage you to wait for our 3.8.4 install later this week, then do a brand new fresh install of Eclipse 3.0.1 and MyEclipse 3.8.4 and then import one of your projects and see if things are better.
I have to agree with leunam that performance can get to be an issue–at least it does on my Windows XP machine (1.7GHz, 512MB RAM) running alongside two or three items of M$ bloatware such as Word or Outlook that are the required tools of my company’s workday. If I close up MyEclipse and restart it, or just use it for a few minutes without switching to another program, I get a temporary reprieve.
I have never had the good fortune to try out MyEclipse on Linux, but I do strongly suspect that the non-responsiveness has more to do with Window’s inefficient memory management than with any specific defect of MyEclipse other than its large memory footprint. I believe this because all the other programs on my machine also become noticeably sluggish just as soon as I use enough disk to start paging memory into the swap-file.
Still, MyEclipse is the worst offender in this regard. Xml files and struts-config files take what seems like forever to become editable again after I’ve come back from reading my email. Given that MyEclipse is dependent not only on Eclipse, but also the Java SDK, there may not be a lot you can do to help speed things up. But be aware that without a desktop supercomputer, people running MyEclipse on Windows out in corporate cubicleville are starting to bottom out, speedwise. Any efforts to avoid contributing to the problem will be greatly appreciated.

This does happen to me a lot on my 512 setup as well, it is frustrating, but unfortunately up to Windows. You can however download the Eclipse “keep alive” plugin that runs a Thread that keeps Windows for swapping Eclipse to disk to avoid this.

This is not what we want. I will kick this thread back to the devs and see if there are known hotspots that we can optimize.
Thanks. Of course, the “easy” solution should be for me to just stick another 512MB of RAM into my PC. But this is corporate America, and to give you some idea of what I’m up against, take a look at this recent Dilbert cartoon:

But even as it is, I love the MyEclipse plugin suite. Now that I’ve grown accustomed to it, I can hardly imagine going back to bare-bones Eclipse. Good show!

The performance of large Java applications on Windows is a known issue because generally Java applications exhibit poor execution instruction locality (they jump around alot) which causes a lot of swapping. In addition, as soon as you minimize an application in Windows, the memory manager swaps out large portions of it. There is a plugin that’s supposed to pin Eclipse in memory on Windows systems and greatly improve performance from Stanford called Keep Resident. I haven’t tried it, but you can find it here:
http://suif.stanford.edu/pub/keepresident/. There are also FreeMem that shows memory usage and provides additional visibility on this available here: http://www.junginger.biz/eclipse/If someone gives this a try please follow up here and let us know how it goes.

Hah, that’s a great one.
