RUBiS is an auction site modeled after eBay.com used to benchmark e-commerce Web site technologies. It is currently used to evaluate design patterns, application servers, and communication layers scalability. Several implementations using PHP, Servlets, Enterprise JavaBeans (EB BMP, EB CMP, MDB, SB, EJB 2.0 CMP, Session Façade, etc.) are already available and new versions for JDO and .Net are currently developed.
SmokePing is a network latency monitor. It measures network latency to a configurable set of destinations on the network, and displays its findings in easy-to-read Web pages. SmokePing has support for distributed monitoring as well as for dealing with dynamic IP addresses. SmokePing uses RRDtool as its logging and graphing back-end, making the system very efficient. The presentation of the data on the Web is done through a CGI with some AJAX capabilities for interactive graph exploration.
System and Process Monitor in Java provides a JNI (Java Native Interface) implementation for monitoring global system resources and processes (outside JVM) via a unified (cross-platform) interface. The Java interface and all native libraries are compiled into a single JAR and are loaded transparently on any architecture upon request. It should be easy to embedd this code into your Java applications, either as a separate JAR or as one single application archive.
Python Tracer lets you see your Python program's execution as a tree of function invocations, each tree node exposing the real time and CPU time (user/sys) of that call. The project consists of two main components: a Python tracer that can run your Python programs (much like "cProfile" and friends), and a GTK+ based GUI that can show the trace results. It uses a tiny auxiliary library (graphfile) to allow append-only writing and reading static DAGs directly from a file without reading it whole into memory at any stage.
cdck is a simple program for verifying CD/DVD quality. Even if all files on the disc are readable, some sectors having bad timing and could become unreadable in the future. The tool reads a disc sector by sector, recording all reading timings, and then tells you its verdict. It can optionally write a timing table into a text file usable by gnuplot, from which graphs can be drawn.
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.
