Utility to test the real block size of storage media. Mostly flash (SSD) drives use larger block sizes than 512 bytes and emulate the sector size which may cause severe performance degradation. This tool helps determine real block size. See wiki.
The fs_mark benchmark tests synchronous write workloads. It can vary the number of files, directory depth, etc. It has detailed timings for reads, writes, unlinks and fsyncs that make it good for simulating mail servers and other setups.
The DTraceToolkit is a collection of over 200 useful documented scripts for analysis of system and process behaviour. It allows in-depth inspection without disturbance of the system.
nfsreplay is a tool to replay Network File System traffic. It can be used for server and client benchmarking under a wide range of workloads. It allows temporal and spatial scaling of the original trace.
Control Plane is a benchmark for telecom application environments. It's implementation uses two major software packages: OpenSER and IMS Bench SIPp to compare performance of distinct systems.
This is a simple LDAP benchmark tool. It creates a number of threads and every thread tries to connect to the Server and does a different query x times. Then all the errors and the time are counted. Through this the religability of LDAP should be tested.
C2CBench (Cache-to-Cache Benchmark) is a tool to evaluate cache to cache performance on modern parallel microprocessors. It measures the performance of accesses to remote caches and the impact of cache coherence protocols on cache-to-cache data transfers
Low-level processor benchmark for x86 and amd64 processors: measures exact latency and throughput for each assembly instruction, and automatically finds execution units. Special focus on SIMD (MMX, SSE) instructions.
Bertha is an I/O benchmark tool for high-end storage subsystems. Based on Tim Bray's Bonnie benchmark tool with three enhancements: 1)it generates far more I/O, 2)it offers a facility to replay I/O transactions”, and 3)extensive metrics reporting.
A program to draw (and save the results to files) a diagramm that shows the execution time of a programm, which does some floating point calculations, in dependency of the number of used threads.
It saves the result as a gnuplot file and a CSV file.
Xdd is a command-line based tool for measuring and characterizing disk subsystem I/O on single systems and clusters of systems. It is designed to provide consistent and reproducible performance measurements of disk I/O traffic. This repo has 6.2a which is really old an obsolete.
The name XDD is trademarked and belongs to
I/O Performance, Inc.
This project is an approach to automating the testing of performance properties of complex systems.Just like functional specs for software we aim to develop an executable language for asserting performance expectations of a program.This implements Sharon
lsstack is a Linux implementation of the "pstack" utility from Solaris
lsstack is a commandline utility which (efficiently and quickly) prints the call stacks for all threads in a specified process,
with symbolic names for functions, where symbols ar
SSLider is a web server benchmarking and testing tool supporting HTTP/HTTPS, cookies, data submission via POST, and scripted site tests suitable for CGI application and servlet testing.
Project aims to simplify Linux kernel analysis and development. Primary audience to the result of project will be (under)graduate students attending "Operating system" courses. It is our intention to make advances with every generation of students.
