The command to test system performance is entered into the docs as htparm -tT The command requires a device after that, so to be consistent with the rest of (incredibly well done) docs, it should be: hdparm -tT /dev/hda I don't know if there is any other advice for getting back to where you were before you did the next few tweaking lines? I lost a few MB in speed when I tried the safe optimizations. I just lived with it Reproducible: Always Steps to Reproduce: 1.Go to prompt 2.hdparm -tT 3.Utter "Damn, he's right" :) Actual Results: Command did not work Expected Results: hdparm -tT /dev/hda
Damn, he's right... Fixed :) I don't know how to get to the original settings, I assume that you need to get information on the settings, write them down, then do some various tests and if none of them prove to be better, take the original settings again. It should be noted that, if you run "hdparm -tT /dev/hda" several times, you will get a better look on the performance as the tests aren't real benchmarks -- they also depend on your current system state.
