Performance
of WhizzBee Web Server 1.0a
[Note:
These results are obsolete, the performance of WhizzBee Web
Server 2.0 can be found here.]
We
have carried out a series of benchmark tests to gauge the performance
of WhizzBee
Web Server 1.0a. We were interested in how WhizzBee
improves with increasing number of nodes in the cluster and
a comparison between WhizzBee and TurboCluster
Server (TC), a similar product in the market. We
used WebBench
3.0 for the tests.
The
results we obtained showed that WhizzBee achieves better scalability
and performance than TC in all except two cases (1 and 2 server
nodes with local datasets) where the performance gain is not
enough to offset the overhead due to cooperative caching. But
the performance gains with more nodes were tremendous: for an
8-server-node cluster, WhizzBee outperforms TC by as much as
15 times for NFS-mounted data. Details of the experiments and
results can be found in WhizzBee
Web Server 1.0a Technical Overview. The following
are copied verbatim from that document, where "TCS 4 +
Apache" represents TurboCluster Server 4.0 with Apache
1.3.14. The last graph, Global cache hit ratio, shows the effectiveness
of WhizzBee's cooperative caching in utilizing memory that is
physically distributed.
