Question

Do I need to upgrade Ram or CPU? (see screenshot)

http://i63.tinypic.com/slhdg9.jpg

I've monitored CPU and Ram usage for some minutes while intensively using my old Asus K52f. As you can see from the picture, RAM is always full and CPU has lots of spikes reaching 100%. Do you think upgrading RAM from 4GB to 8GB would produce any noticeable improvement, considering CPU is intensively used as well?

Re: upgrade

That might depend on the programs you run to get all that CPU and RAM usage.

If you look at this recent video.

You'll spot the i9 desktop CPU and the enormous amount of RAM plus the GPUs still being used at near 100% levels.

So it appears that you have to go to the extremes to avoid 100% use but is it worth it?

My thought is for the k52f you could turn the laptop into a better laptop by changing the HDD to SSD and up the RAM as you noted. But you will still see 100% use at times.

Some more clarifications...

Thank you very much for the replies!

Of course, I don't care about the 100% spikes themselves, the problem is, my laptop slows down A LOT when CPU goes to 100%.

By the way, I'm running win 7 64 bit. During the observed period I was using Eclipse IDE while playing a YouTube video full-screen on Chrome, having Tomcat server and MySQL database running.
The spikes happen when I play/pause the YouTube video or when executing some Eclipse function.

So, if I do upgrade RAM, do you think CPU will still go to 100% but laptop won't slow down that much?

Re: slowing down

So does my (professional) laptop if McAfee's scan of all files is executed once a week (set so by the IT staff).

With that workload you should certainly do both: a faster CPU and more RAM. Only a benchmark will show what has the most effect in which situation.
Which, in practice, means a new PC. Or, even better, a second PC to serve as server for MySQL and Tomcat in your home network. Or maybe a smart TV or an Android box to view Youtube on while working at the PC.

In that case, no.

You only have so much CPU and the load you wrote about is going to tax this old machine no matter what you do. Maxing out the RAM won't cure the load issue. It can help as well as the MORE IMPORTANT move to SSD.

If you have a HDD, a big chunk of the speed loss is in the HDD activity.

Thank you very much for all the replies.
The processor is Intel Pentium CPU P6100 @ 2.00GHz. Video card is Intel HD Graphics. I've already upgraded HDD to SSD and noticed quite an improvement in performance.

Then the next step

Is more RAM. 4 to 8 is your big payback. 8 to 16 rarely has folk telling me it felt faster.
