Running the PostMark disk benchmark resulted in Calculate Linux Desktop winning on the AMD system side with it coming out about 14% faster than Sabayon and Ubuntu, which were tied for second place. Fedora 13 was the slowest Linux OS on both operating systems and Calculate Linux Desktop was a whopping 51% faster with the triple-core system. Ubuntu 10.04 LTS knocked Calculate Linux Desktop 10.4 to second place on the 32-bit netbook.
Running another disk benchmark, which measured the time to compress a 2GB file using Gzip, the AMD results were nearly the same while there was some fluctuation with the SSD-based Atom netbook. Fedora 13 was the fastest on the OCZ Core Series SSD + Intel Atom N270 followed by Ubuntu, Calculate, and then Sabayon.
Lastly, with the Parallel BZIP2 compression results, when looking at the Samsung NC10 numbers the fastest was Calculate Linux Desktop 10.4, but with the overclocked AMD system the fastest was Ubuntu 10.04 LTS and it put Calculate Linux Desktop 10.4 in last, but with a smaller percentage difference between the four operating systems.
Calculate Linux Desktop 10.4 won a few of our fifteen benchmarks that were carried out for this four-way Linux performance comparison, but it was not the clear winner over Ubuntu, Fedora, or the fellow Gentoo-based Sabayon. In at least the tests that were carried out, there was no conclusive performance advantage to running Calculate Linux on either the Intel Atom or AMD Athlon II systems that were benchmarked within our test labs.
The tests where Calculate Linux Desktop shined positively were with World of Padman, Apache, C-Ray, PostMark, and Parallel BZIP2 compression. Most commonly, these wins were found on the Intel Atom system with the 32-bit software that Calculate Linux Desktop has i686 optimizations. Most desktop users will not notice a significant speed advantage to using the Gentoo-based Calculate Linux Desktop or Sabayon over one of the other more popular Linux distributions like Fedora or Ubuntu, but if you are interested in trying out a Gentoo-based distribution while avoiding lots of time compiling Gentoo yourself and other headaches, after spending the past few days running Calculate Linux Desktop, we would suggest it as a distribution worth trying.
