1. I have used some of eclipse based IDE for microcontroller. I feel them tad slower/bulky on processor compared to IDE which are written from scratch for embedded application.
Is it me or anyone else have same experience.

2. Like TI's CCS is too slow/blotted compared to keil or IAR.
Keil or IAR have way more better GUI, easy to use & more intuitive.

3. Apart from that I also feel AVrstudio 6 slower. They have given some checklist to make it faster if its slow. But again cannot match keil or IAR in ease of use.

4. Also MPLAB IDE seems slower & less intuitive.


Reason I believe:
1. They are not written from scratch. They are based on some platforms.

2. Every now & then these companies try to add more & more features to their IDE, which I personally feel not necessary, other's might find useful.
like Opening webpage inside it, videos , pdf inside it



(BTW I have 4GB RAM with i3)

 

I used to use eclipse for about 8 hours a day every day and didn't find it slow and I have used plenty of others, not a lot to choose between them. You might be right about the clutter but then it's a whole tool box full of tools rather than a single tool
