My laptop is Dell XPS M1330 Memory: 2GB Processor: Intel Core 2 Duo CPU T5450 @ 1.66GHz x 2 Graphics: Intel 965GM x86/MMX/SSE2 OS type: 32-bit Disk: 500 GB

Updating myself since 12.04 and now currently on 13.04. The performance of my system is now really bad. Slow like anything performance wise.

This is my df -h output

At this moment of output, I have pidgin started configured as office-communicator for Lync connectivity and gmail configured. Further I have Google chrome started with around 7 tabs.

Mainly only this is running upfront.

I need suggestions, please don't make me install OS again as I don't want too and rather it is not a good practice either.

Thanks

If you're looking for an "expert opinion", look at hiring someone, this is community support, answers here have no guarantee of accuracy.

First I just want to note 13.04 is old, 13.10 is the latest version.

You did not clarify what you meant by "performance". Performance in Unity? Performance games aren't running very well? Chrome isn't loading pages fast enough? From the specs you posted, your system isn't exactly a new system. A system sold with 2GB of Ram and Intel GMA graphics is kind of pushing it in a system running the Unity shell, especially one after 12.04 with the decision to drop Unity2D.

It's important before any upgrade you should always backup your stuff (I clone my entire disk to an external drive with clonezilla) as occasionally upgrading may cause an issue depending on how much you have customized your system.

First, I'd suggest to download a LiveCD or make a Live USB copy of Ubuntu and boot it to see if it helps.

However, I think the system might not be completely up to par with newer releases of Ubuntu. I'd suggest in the case of the specs you're using, you should switch to LXDE or XFCE. Unity is fairly bloated contrary to popular belief, especially as time has went on. I prefer LXDE if I want a light environment since it's really lightweight and simple. Plus the Ubuntu LXDE distro (Lubuntu) looks really nice compared to the regular stock LXDE. You can use either command.

sudo apt-get install lubuntu-desktop
sudo apt-get install xubuntu-desktop

You'd need to logout and change the desktop environment by clicking the little ubuntu logo near your login name and choose the desktop you installed.

More than likely, unless you system is messed up in some other way, switching to a more lightweight desktop will make the system much more snappier.

I am also looking for the community support, I am pretty much sure experts around read and comment and help others. Yes I have not yet upgraded to 13.10 as due to some apps I use which I have configured, I doubt they will not be fully supported with 13.10 but this does not mean the performance should drop. I am using gnome and using the lightest option available. Performance issues are, when system turns on the login takes quite long to load everything. The browsers with multiple tabs lags alot etc ... Further I agree the system is old but dude it is Linux –  Faisal Saleem Feb 7 at 12:39
    
The belief that "it's linux" does not necessarily mean it is lightweight, KDE, Gnome Shell and Unity are the opposite of lightweight. By "Gnome" I'm making the assumption you mean Gnome Shell? I still think it's your system you're using, I have one nearly identical & used it exclusively since I don't have much money I switched to LXDE. Like the other answer adds in, Chrome is also a resource hog. Chrome was advertised as being lightweight and fast, at least in the early days, but it is a big hog these days. Plus if you have a lot of plug ins and extensions running that adds to the load. –  jsebean Feb 8 at 13:35

I'm not really "an expert" but it is clear that Chrome is literally eating all your resources. I may recommend you Firefox to replace it, or any other browser that doesn't behave so lusty with your memory and CPU.

Additionally, you can try to free the ram cache if you feel that everything isn't going as it supposed to:

free -m && sudo sync && sudo sysctl -w vm.drop_caches=3 && free -m   

Of course, that is not a definitive solution to your problem and I would also advice you to upgrade your distribution to the latest version.
