I have a Dell Latitude E4310. I have Windows 7 and Fedora installed on it. I rarely use windows and I have been using fedora for a good 9 months now. Recently the performance on my machine degraded considerably. I got a hardware servicing done as well however it continues to worsen each day. What tools can I use to analyze and further resolve the problem?

I have ample of disk space > 30 GB unused.

How do I diagnose a performance problem?

This question is too broad for this website, but I'll offer you the following tips only because I don't want you to feel like you're being blown off.

  1. Consult the output of top. Look for processes that are consuming either a lot of CPU and/or memory resources
  2. Check the output of dmesg, looking for any messages related to errors or anything that's failing
  3. Check log files, specifically /var/log/messages
  4. Make sure you're up to date, yum -y update
  5. Exercise the system using memtest86+

These are just a few of the things to get you started.

Try to use top to see which process consumes the more RAM/CPU. iostat can also be used to see which process uses your disk.
