Hello
I am using Eclipse on a modern laptop which works really well.
I want to run it on an much lower spec laptop but am concerned about the
minimum spec required for adequate performance.
Can anyone tell me what the minimum spec machine (processor type/speed,
RAM, screen size) would be for Eclipse?
Is there an option to run 'eclipse light' on older machines?
thanks
John

It depends very heavily upon:
1. what you consider to be "adequate performance"
2. what modules of Eclipse you are using - in particular, WTP+JDT is much
bigger than JDT alone.
3. how big the projects you're working on are.
Because of those variables, you are unlikely to get a crisp answer to your
question. But if you tell us more about what you're hoping to do (in very
specific terms, e.g. "Java development in a workspace with approximately 10
projects each containing approximately 100 Java source files of average
length 1000 lines"), perhaps someone will be able to share some relevant
experience.

I agree with this response. I will add a couple of things, however:
A) Generally speaking, older versions of Eclipse are slightly better on
older hardware than the newer versions. It is not a drastic difference
but you might try a 2.x Eclipse if you can sacrifice the features and
usability enhancements in the later versions (not likely if you ask me,
but maybe for some users it is acceptable)
B) Also generally speaking (and assuming the latest Eclipse), I'd say
you'll need a minimum of 128MB of *available* RAM after the operating
system has taken what it wants. If you run other apps, such as Firefox
or a database or Outlook or ..., ones that use a lot of RAM themselves,
you'll have more problems with swapping which can make any application,
including Eclipse, slow to a crawl. In short, on a Windows machine 512
total RAM is probably the usable minimum. The processor is not as
important - I've used a Pentium III on the 2.x family of Eclipse and
Pentium 4 with Eclipse 3.x and it was quite usable.
Hope this helps,
Eric

Hi
Thank you both for your comments. I will be using Eclipse for Java J2SE
and J2ME and possible C/C++ proejcts. I would not expect the need to have
more than 5 projects open at one time, projects will be order of 50
classes.
There are two machines I am thinking of:
1) I have an old but really nice laptop with a 1024x768 screen Pentium II
333Mhz but only 128Mb RAM - it runs Linux/X fine but I wonder about
Eclipse, perhaps an older version without WDT and nothing else happening...
(will have to look into how to disentangle the WDT and other modules that
are bundled in eclipse) I will experiment and report back.
2) I'm interested in the idea of running Eclipse on something ultra
portable like the OQO - this has a 1Ghz transmeta processor and 512 MB RAM
with an 800x480 screen. From what you say, this could will be a
possibility, although I notice a bug report saying some dialogs need at
least 800x600 (the fix is to update the readme!)
http://www.oqo.com/store/shop.cgi/op/op_itemdetail.html
Im also interested in looking into novel UI inputs (using touchscreen) to
facilitate development 'on the go' - particularly refactoring. It would be
more about intelligent editing than a full (fast) compile and debug
environment - would that help in turning some eclipse features off to make
it run better?
Would be very interested to hear from anyone who has run eclipse on such a
platform.
Cheers
John

In addition to that, I'd suggest that RAM is a much bigger issue than
cpu speed. I have a fairly small eclipse installation, with 4 projects
*totaling* approx 100 source files, and the combination of eclipse.exe +
javaw.exe can easily grab 250MB of memory, according to task manager.

If you can add more RAM to bring it up to 256MB, that would probably be
fine. You can always try it and see if it meets your needs...
