Apache Hello World Benchmarks is a benchmarking tool that seeks to give a sense of Web application execution speed on various software platforms running under the Apache Web server. Benchmarks can vary greatly from system to system, so this tool allows one to get numbers on one's own platform. Applications tested include mod_perl, mod_php, Tomcat, and Apache::ASP, with over 62 benchmarks in all.
sdb is a really simple program to benchmark disks. It only writes/reads data sequentially to/from a file and calculates the performance of this action. A memory buffer is used for input/output to get values close to the real performance of the disk or RAID system. You can use flags like O_DIRECT and O_SYNC to avoid buffering by the operating system. It is similar to dd, but there are some differences, since dd was not created for benchmarking a disk. It is possible to initialize the buffer with random values before writing them to the disk or a file on the disk. It is a simple but effective program to get the maximum speed of a disk. Due to the simplicity, you will get the results much faster than with a more complex benchmark.
This release is based on the Unix port of beta release 2 of BYTE Magazine's BYTEmark benchmark program (previously known as BYTE's Native Mode Benchmarks). The port to Linux/Unix was done by Uwe F. Mayer. Additional changes to the code were made to make the code work with egcs compiler and to make the software packagable. This is a CPU benchmark providing indexes for integer, floating, and memory performance. It is single-threaded and is not designed to measure the performance gain on multi-processor machines.
The NAS Parallel Benchmarks (NPB) are a small set of programs designed to help evaluate the performance of parallel supercomputers. The benchmarks, which are derived from computational fluid dynamics (CFD) applications, consist of five kernels and three pseudo-applications. The NPB come in several flavors. NAS solicits performance results for each from all sources.
Aranha is an application that uses an XML-RPC layer to retrieve information from one or more servers. The type of information gathered is implemented via plugins, and can be displayed or archived in several different ways. The data is gathered in Round Robin Databases (integrated with rrdtool) and can be accessed using a XUL interface available from the system. Plugins are very easy to write.
