“For looking more at the FreeBSD performance we also
have included test results from FreeBSD 7.2, the current stable
release. In this article are mostly the server and workstation
oriented benchmarks with the testing being carried out on a dual
AMD Opteron quad-core workstation.“Among the new features to be found in Ubuntu 9.10 include
performance improvements in several different areas (as shown by
some of our benchmarks), integration of the GNOME 2.28 desktop,
usage of the EXT4 file-system by default, updated X.Org packages,
the Linux 2.6.31 with its plethora of new features and drivers,
many minor usability fixes, and other changes for this six-month
update to Ubuntu 9.04. With FreeBSD 8.0, which will arrive about
five months after the release of FreeBSD 7.2 and just a few months
shy of two years since the release of FreeBSD 7.0, brings improved
ZFS support, Xen DomU support, a rewritten TTY layer, a new USB
stack, NFSv4 support, network stack virtualization support,
superpages, an experimental new driver for AHCI, D-Trace
improvements, ULE 3.0 (improved SMP-optimized scheduler), support
for light-weight kernel threads, and many other changes.”
