Poor Performance

[emer_son]

Hello Everybody
I've been using Kubuntu 8.04 since it came out. At first HDD performance seemed satisfactory. Lately performance in opening apps as welll as making disk data transfers has been slow. I've read other posts about hdparm but was unsure they applied to hardy. I have a 250 GB sata drive with athlon x2 2600 cpu. Any suggestions would be appreciated

Thanks

Re: Poor Performance

Before assuming the performance issue has anything to do with the hard drive(s), open a console window and issue

top

Then observe the usage of CPU and memory resources, and post the top 5 with their percent of CPU used.


Also, here's some light reading that might be relevant:
