My computer (Sony Vaio VPCF22S1E) has Inter Core i7 (2GHz) processor, 8GB RAM (details) . There are 2 operation systems on my PC . Windows 7 and Ubuntu. My computer's performance was great, a few months ago. But now it's very slow. Windows is faster than Ubuntu, but still Windows is really slow, too. Also, my battery is empty in 45-60 minutes
Actually, i'm not using Windows 7. I'm using Windows 2 or 3 hours in a week (I'm studing Computer Engineering and sometimes i need it, but generally i'm working with Ubuntu) .
I think there are a few applications which cause slowing down Ubuntu . My question:
- How can i list all applications which open currently ? Maybe they are slowing down my system ?
- Recently i'm using Ubuntu 11.10 32 bit. If i install 64bit version (my processor supporting 64bit) , has it more performance than 32 bit ?
- Should i remove Windows 7 from my PC ? I'll use Windows inside Ubuntu with a virtual machine, if i remove Windows 7.
Thank you,
Details:
Recently installed OS' : Ubuntu 11.10 (32Bit) , Windows 7 (64Bit)
