Xserve G5 server- and cluster-optimized system
architecture includes 64-bit G5 processors, a superfast memory
architecture and a high-bandwidth I/O system. And these powerful
hardware features are enhanced by the industrial-strength Mac OS X
Server, optimized for superior performance on Xserve G5 systems.
 Blasts the
Competition. BLAST, a popular tool used by life science researchers
to find matches in DNA and protein sequences, demonstrates the
advantages of Xserve G5 for processor intensive scientific analysis.
Different word sizes are used for different kinds of research, and
users can adjust word size to the sensitivity appropriate to their
needs. In common searches using a word size of more than 11, Xserve G5
far outperformed the Xeon-based servers. Even at word size 11, for
which NCBI BLAST has been extensively optimized, Xserve G5 performs on
par with the competition.

 Tips the Scales. Apple
tested the scalability of Xserve G5 storage using Bonnie++, an open
source benchmark that measures drive throughput.This test shows that
both read performance and write performance improve as drives are added
to the system.

 Keeps on Humming. HMMer also
demonstrates the power of Xserve G5 scientific analysis. HMMer uses
Hidden Markov Models (HMMs) to identify similarities in genetic
structures. To test Xserve and the competition, Apple searched for an
HMM created from a 358-residue sequence in the protein databank (PDB)
and measured the time to search the entire PDB. The dual 2GHz Xserve G5
performed the HMMer search up to 33 percent faster than the 3.2GHz
Xeon-based servers and 69 percent faster than the 2GHz Opteron-based
server.

 Cleans Up Windows. With
more than 12 NetBench clients, Xserve G5 with Mac OS X Server beats
Windows servers at their own game, delivering Windows file services
significantly faster than the Xeon-based server with Windows Server
2003. Its performance remains high even as clients are added to the
network, thanks to an I/O architecture optimized for server tasks.
Xserve G5 provides the best balance of processor, network, and disk
performance — critical for delivering file services to large numbers of
network clients.

 Zips Past Linux. Xserve
G5 easily supports a large number of network connections. WebBench from
eTesting Labs demonstrates the superior web server performance of
Xserve G5 based on the number of connections each server can support.
With more than 16 WebBench clients, it smokes the Xeon- and
Opteron-based servers. You'd expect that, since Xserve G5 features dual
onboard Gigabit Ethernet controllers, as well as optimized network
drivers and a high-performance BSD network stack in Mac OS X Server.

Performance
tests by Apple, January, 2004.
Apple performed the NetBench and WebBench tests without the supervision
or verification of eTesting Labs, which makes no representation or
warranty of the results. eTesting Labs WebBench version 4.1 was used
with the standard test suite STATIC_WB41.TST, with the threads variable
set to 5 and with 28 client computers. For the WebBench test, Xserve G5
ran Apache 1.3; the IBM systems ran Apache 2.0. |
