I installed 8.04 onto a brand spanky Dell Poweredge 840 - 2.4Ghz dual processor, 1TB disk space on 4 SAS drives, 4Gb RAM. It ran like a dog with its back legs chopped off and tied to a jumbojet flying in the opposite direction. Switched off server and waited for 8.10. Wiped drives all down so there was no remains of the previous incarnation and tried again. Clicked the buttons ;-) let it install, went and had a cup of tea and the watch a bit of telly ;-p, came back a while later and the server was ready. One reboot later and ran the updates and my Ubuntu Server is finally complete. Now it runs like a greyhound on steroids. I am a happy bunny! Now to install VM Ware and some MS crapola and I finally have a decent system I can work from without it crashing like a S.O.B.
Its definitely improved, maybe not as much as some people would like but mostly, its FREE!
I havent paid for a stupid MS license and had them screw up my system!
People, if you dont like what you see on the OS, get your finger out of your ass and learn something about the system, find out what you can do to improve it and make it happen.
I'm not a fanboi, I usually hate them all with the same passion but at least if i dont like it or doesnt do what I need it to, I can find out how to change it AND I HAVENT PAID ANYTHING FOR IT!
Enjoy for free, or go buy something else!
