We use one server and several PCs to test [EMAIL PROTECTED]'s performances. The
server has two Xeon 2.4GHz CPUs (disabled the hyperthread function), 2 GB DDR2
memory, one 37 GB 10000 rpm SCSI hard disk and a Gigabit Ethernet network
adaptor. Client PCs have a Pentium 4 2.0 GHz CPU, 512 DDR memory, one 40 GB
5400 rpm hard disk and an integrated 100 Mb Ethernet network adaptor. Testing
tools are SPECweb99 and Benchmark Factory.
We use SPECweb99 to experiment 300, 600 and 1000 simultaneous connections on
four testing platforms including the [EMAIL PROTECTED] on FreeBSD v5.3, Apache
v1.3.3 on FreeBSD v5.3, Apache v1.3.3 on Redhat Enterprise Linux v3.0, and TUX
3.2.14 on Redhat Enterprise Linux v3.0. All these environments setup and
configure by default and without any optimization. Since OpenKETA just
accelerates the static HTTP requests, we have set the dynamic request ratio to
0.0 in SPECweb99’s rc file.
NOTE that: The experiments tests all are just on the default OSs Settting and
without any optimizations.
