Both are full

While the memory usage is high please run:

  ps auxw > ps.txt
  free -m > free.txt

and then attach the resulting text files here.

[Daniel van Vugt (vanvugt)]

Thanks. It's hard to tell because ps.txt is cut off on the right for some reason. But it seems Google Chrome tabs are your main problem. I suggest just close some tabs :)

Also Firefox and Skype are using significant memory so close those if you can.

This does not appear to be a problem with Ubuntu.

What Can I do to improve, because When I was using windows with same (bit more) apps and load it was working fine, but I thought Ubuntu will might even better,
But I think there is something wrong with this system or my installation,

Could you please suggest some workaround if you can? What I should do .

[Daniel van Vugt (vanvugt)]

You need to close your browser tabs and/or close some apps.

It's certainly possible Windows copes with such stresses better than Ubuntu does. To investigate that further you might want to try adding more swap space or even disabling swap, as some people claim the Linux kernel performs better that way:

  sudo swapoff -a

If all else fails, please just reduce the number of browser tabs you have open, close some apps, or add more RAM if your laptop allows for more to be added.

Ok, Thank you. :)
