    Default Eclipse

    I use eclipse for writing the small programs that I make and at first it was great though now it lags and frequently stops responding for some seconds. It's pretty annoying and I'm not sure where I could be going wrong since the laptop is new.

    What do you guys think could be the problem?

    Does your computer suck? Maybe you're running too many things at once? I have some very tiny issues with eclipse that happen every once in a while but for the most part, Eclipse works just fine for me. That may or may not have to do with my beast of a pc, but thats besides the point.

    What programs are you writing? Are you leaving something running in the background? Got a thread in a loop?
    Take a peek at whats running when it seems laggy and try to determine what is hogging the cpu.
    Ask the system to tell you how much RAM is available. Laptops usually have lesser quality chips from the get go and them going bad is common.
    So many options. Do some research and see what clues you can find and post back if you have problems.

    Laptop is pretty good and a couple of weeks old with good memory, internet connection is pretty slow though unrelated.
    I'm going through project euler problems. I'm new to windows 8 so I may be leaving things on in the background, I'll do some research on how to check etc.
    Thanks for the advice.

    By that I meant if you are working with threads/loops, you may have a loop creating objects endlessly or something of that nature. It is hard to say exactly without something to go on.
    One thing I learned about new things is that they are new, but this does not mean they are good. Make sure you actually check the total amount of RAM. For what you describe this is a definite possibility. More so than a faulty program, as such a thing would generally cause the JVM to exit or crash instead of just run slow.
    How much RAM does it have and what are you running? Perhaps the RAM is all good but just not quite enough for everything to be open. What size programs are you running? Some of the euler projects are pitfalls/traps that help to teach a point.
    Good luck with your search, if you find the problem post back what it is

    6gb with around 5.8gb usable.
    cpu usage is 99%, with eclipse running 126 threads for some reason using 20-45%CPU,the rest of CPU taken by javaw.exe programs each taking around 20-30% cpu. I've only got 2 java projects as I deleted the rest so not sure. I'll try and find out how to delete those threads.

    If sounds like you've got several spawned processes that we're never properly terminated. For instance, if you are running in Eclipse and your code enters an infinite loop, if you do not terminate the process it will continue. Do this a few times and you may push your CPU to its limit. You can manually try and terminate them all, but would probably be easier to just restart your computer. Give it a try, launch Eclipse and inspect the usage thereafter.

    I restarted and cpu down to around 8%, still not responding sometimes though far better than before. I'll keep the thread open just in case more problems come up in future.
