The performances of OpenKeta@FreeBSD v0.8-alpha

[iampinetan at netscape.net]

We use one server and several PCs to test OpenKETA at FreeBSD'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 OpenKETA at FreeBSD 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.
