We need to update our webserver (PIII-700MHz and 512Mb RAM) and could not do that without reinstalling the whole system. However my choice to put Ubuntu 9.10 was probably not the best and the machine works very slow now. Actually, we need it just for simple LAPM configuration and we really want to use the old box for this purpose. It used to have old version of Linux Slackware in which I didn't manage to update PHP due to a very complicated non-standard setup.
What would you recommend?
Update
OK, thanks for your answers! Based on them I got an idea that it is possible to avoid loading X11 and other heavy stuff on Ubuntu9.10 and make it running. Actually, I was going to setup Ubuntu Server package, however something went wrong during Ubuntu9.10 installation (at 23%), which I recognized as insufficient resources.
Could you confirm that one can use Ubuntu9.10 with this configuration (PIII-700MHz and 512Mb RAM)?
Final update
I appreciate all answers; thank you, guys, for your help. I have tried to reinstall Ubuntu Server, however, the installation process failed twice. A memory test has discovered that there are failures in the old memory units. After I have replaced them (and also some coolers which has stopped to work in a while - old stuff), I have successfully completed the installation. However, after restart I've got an error message that GRUB cannot find a partition. That was the last drop and I gave up not even trying to find why. We will better order a VPS, as we find out that the IT department in our company is now introducing such service. I am sure that your tips will be needed by other guys.
