Slow performance on Hoary/Gutsy

[Anna EdwARds]

If i were you, i would back up anything of any importance and reinstall 7.04 if you can find it and wait untill the next lts (following old pattern it should be 8.06) and then stick with lts editions. If you want a 7.04 disk i have plenty to spair just give me a shout.

Subject: Slow performance on Hoary/Gutsy
---

I have a very slow performance on my system. The machine is somewhat aged; it is a Nvida Nforce 2 with a AMD Athlon XP 2000+ CPU and 1GB RAM. I have used Ubuntu since version 5.04, I do not know if I just need to take this degradation into account? With Hoary I did a new install for the first time since April 2005. Previously I always used the upgrade option. After the install I noticed that the harddrive is identified with as a serial ATA drive, although I am confident that this old drive is does not have a serial ATA interface. Could this be the reason for slow performance? DMA seem to be enabled from what I can see. 

I am grateful for all sorts of advice before I resort to buying some new hardware.
