It's a fairly fresh eclipse install, and I just boot it up. It showed
the home screen, no project loaded. It was doing absolutely nothing and
well into 400mb.
When I do use it for android and appengine, it more or less works well
enough, but the UI feels like it's held together with stickytape and
glue, and it's pretty sluggish. Debugging (native code) is slow and
clunky. How can I take that software seriously?
I probably waste significant portion of my life hovering and waiting for
eclipse to render the pop-up variable inspection windows. That shit
needs to be instant, no excuse. It's just showing a value from ram.
Then I press a key, it doesn't take ages for the letter to appear on the
screen...

Android and Appengine?
There are two flaws in that comparison, the first is that apparently you are comparing an Eclipse installation with a lot more tools than your VS installation (which I'm guessing has only C++ tools, perhaps some VCS tools too?). No wonder the footprint is bigger. For example, my Eclipse instance with only DDT and Git installed, and opened on a workspace with D projects takes up 130Mb:

My VS installation has VisualD, VCS tools, xbox 360, ps3, android, emsscripten, nacl, clang and gcc tools. (I don't think these offer any significant resource burden though, they're not really active processes)
If Eclipse has a lot more tools as you say, then it's a problem is that I never selected them, and apparently they hog resources even when not being used. That seems like a serious engineering fail if that's the case.
As far as I know, I don't have DDT and git installed, so you're 2 up on me :) .. I only have android beyond default install (and no project was open). No appengine in this installation.

With the recommend JVM memory settings (see http://code.google.com/p/ddt/wiki/UserGuide#Eclipse_basics ), the usage in that startup scenario goes up to 180Mb.
But even so that is not a fair comparison, the second flaw here is that Eclipse is running on a VM, and is not actually using all the memory that is taken from the OS.

It's perfectly fair. Let's assume for a second that I couldn't care less that it runs in a VM (I couldn't), all you're really saying is that VM's are effectively a waste of memory and performance, and that doesn't redeem Eclipse in any way.
You're really just suggesting that Eclipse may be inherently inefficient because it's lynched by it's VM. So there's no salvation for it? :)

If you wanna see how much memory the Java application itself is using for its data structures, you have to use a tool like jconsole (included in the JDK) to check out JVM stats. For example, in the DDT scenario above, after startup the whole of Eclipse is just using just 40Mb for the Java heap:

I don't care how much memory the app is 'really' using beneath it's overhead. All I care about is how much memory it's using (actually, I don't really care about that at all, I only care about how it performs, which is poorly), and the windows task manager surely offers the most fair measure for comparison available to the OS, at least for the memory consumption metric ;) .. The problem remains that I find eclipse significantly less responsive, and the UI is messy and disorganised. I feel a lack of coherency between different parts of Eclipse.
So in summary, I prefer and use VS whenever I have the option.

I had some experience with kdevelop this past weekend trying to find a reasonable working environment on linux. It's fairly nice. Certainly come along since I last tried to take it seriously a year or 2 back.
It would be nice if there was D support though. It has rudimentary support that some whipped up, but it could do a lot better.

Can any linux MonoDevelop user enlighten me on how to use MonoDevelop4 on linux? I couldn't find a package for it anywhere... only MD3. It seems linux MD is way behind... no idea why.
