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.
