"We were using Arch Linux 2009.08 (x86_64) with the Linux 2.6.30
kernel, GNOME 2.26, X Server 1.6.3, the NVIDIA 185.18.31 display
driver, GCC 4.4.1, and an EXT4 file-system. In comparison, with our
Ubuntu 9.04 (x86_64) tests were the Linux 2.6.28 kernel, GNOME
2.26.1, X Server 1.6.0, NVIDIA 185.18.31, GCC 4.3.3, and an EXT3
file-system. Our test system was an ASRock NetTop ION 330, which
packs an Intel Atom 330 CPU, an ASRock AMCP7A-ION (NVIDIA MCP79)
motherboard with GeForce 9400M graphics, and 2GB of DDR2
memory.
"The benchmarks we ran for this quick comparison were World of
Padman, Apache Benchmark, Ogg Encoding, timed HMMer Search,
Threaded I/O Tester, PostMark, Dbench, GraphicsMagick, dcraw, and
SQLite. With this testing we are just providing a quick overview of
how -- in general -- Arch Linux compares to Ubuntu. If you would
like to compare the performance of Arch Linux to other
distributions or look at the performance in more detail, try out
the Phoronix Test Suite."
