Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I have a powerful machine with 32GB RAM, 10TB hard disk storage, and an Intel Core i7 3.3Ghz processor. We installed Ubuntu Server 11.10 and tried some scripts: the most impressive was a sort file.txt | uniq -c on a text file of 2.2GB. It took around 4 minutes.

After that we installed Slackware 11.37 and the same script finished in less than a minute on a text file of 2.2GB.

Do you guys have any idea why that is? On every study we saw before always Ubuntu performed better than Slackware.

Both installations are default: Ubuntu with GNOME and Slackware with KDE.

Are these two text files identical? –  G. He Apr 25 '12 at 21:01

Wait. Why did you have GNOME installed on Ubuntu Server... ? –  Jjed Apr 25 '12 at 21:21
    
Yes mate, the files are identical. –  Luis Henrique Apr 25 '12 at 21:23
    
We had GNOME installed on Ubuntu Server because we need a x interface mate. I tried it on normal Ubuntu too. –  Luis Henrique Apr 25 '12 at 21:24
    
Can you post links to some of those studies. –  mikewhatever Apr 25 '12 at 21:29
