This question already has an answer here:

I love Linux and I think it is the best OS out there, but for some reason it is noticeably slower than windows 7 on my machine. It hangs a lot, and none of the animations are smooth. It is a HP pavilion dv9700 laptop. I have 2 gb of ram and a dual core intel processor. I will add the hardware output from lshw in the end of this question. I hope you can help me because I really love the Linux philosophy and don't want to have to go back to microsoft and windows.

PS: I tried Mint and Ubuntu and also installed the XFCE and LXDE versions of Ubuntu. Still it lags a lot, which shouldn't be so bad with my specs I think. I guess it may be a compatibility problem, but I can't put my finger to it. That's why I will add my specs in the lshw at the bottom, maybe you guys can find the problem?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Which version ? – 22lk94k943 only May 14 '13 at 17:53
Could you add the output of glxinfo | grep render? – Braiam Sep 9 '13 at 15:28
@user158656 Have you enabled additional drivers? – Archisman Panigrahi Oct 29 '13 at 6:03
@ArchismanPanigrahi I would rather suggest that the animations aren't smooth because of non-optimal closed source drivers. That was my observation with Unity. – LiveWireBT Oct 30 '13 at 8:01
On the other side if you take a coser look, this was already a low end machine when it was released (Pentium was a low end brand by then already). No surprise here. Slow speed and stability in comparison to Windows 7 is partly due to bugs in desktop components and partly opinonated. – LiveWireBT Oct 30 '13 at 8:07

I tried Mint and Ubuntu and also installed the XFCE and LXDE versions of Ubuntu. Still it lags a lot.

I don't know the details, but in such cases is either, graphics card incompatible (if it's only the animations and no the real RAW performance) or a hardware failure, like memory or HDD.

Troubleshooting this may prove not be easy. You need to install the privative Nvidia drivers if you haven't done so. If you don't see improvement in the graphics performance, then be almost assured that is bad RAM modules or the Hard Disk failing. The hard disk can be tested if you use a Live system (should be USB to properly measure the fastest performance, since CD's are slow), bad memory modules come often accompanied with other random errors but it worth a shot testing it.

As a final test, you should also check if your BIOS settings are optimum, and the BIOS is updated, your laptop isn't filled with dust (dust tends to traps heat, and the system throttle performance when hot).

You should probably noticed by now, that I could still list more reasons, since system performance could be affected even if the combination of hardware components/software is not adequate and finding out the perfect balance is, well... difficult.

Upvote for suggesting checking memory and dust cleaning. – LiveWireBT Oct 30 '13 at 8:06

You will seldom get optimum speed with dual boot, but it should be good at most of time.

You may have to clean RAM from within ubuntu and reboot to ubuntu first.

To clean RAM

As root

#: free -m verify actual RAM status

#: sync Force changed blocks to disk, update the super block.

#: echo 3 > /proc/sys/vm/drop_caches Writing to this will cause the kernel to drop caches, dentries and inodes from memory, causing that memory to become free.

how does dual boot reduce speed? AFAIK, it only eats more HDD space and nothing more. After GRUB menu you have single OS loaded! – Stefano Mtangoo May 14 '13 at 19:35
I am not even running dual boot, I always do a full install. So that couldn't be the problem. – user158656 May 14 '13 at 19:52
@Stefano In dual boot Both OS use RAM simultaneously that makes many programs load slower then they should. – 22lk94k943 only May 15 '13 at 4:30
@user158656 there may be another reasons too. A hard disk problem may give such result, check with a Hard drive utility from the manufacturer. And if it's Raring you talking about then try to update the kernel to mainline 3.9 – 22lk94k943 only May 15 '13 at 4:35
Dual booting does not cause the operating systems to share any resource besides hard drive space; nor is the OP dual booting. – Travis G. Oct 29 '13 at 0:32
