Several tools with combined sampling and call-graph profiling. A set of visualization tools, VCG tools, uses the Call Graph Drawing Interface (CGDI) to interface with gprof. Another visualization tool that interfaces with gprof is KProf. Free/open source - BSD version is part of 4.2BSD and GNU version is part of GNU Binutils (by GNU Project) HWPMC
[7] Mozilla points out that the performance of natively compiled code is not a single measure but rather a range, with different native compilers (in this case Clang and GCC) delivering code of differing performance. "In fact, on some benchmarks, like Box2D, FASTA and copy, asm.js is as close or closer to Clang than Clang is to GCC. In one case ...
LoadRunner is a software testing tool from OpenText.It is used to test applications, measuring system behavior and performance under load.. LoadRunner can simulate millions of users concurrently using application software, recording and later analyzing the performance of key components of the application whilst under load.
The software is designed to be used as a load testing tool for analyzing and measuring the performance of a variety of services, with a focus on web applications, APIs, and microservices. Gatling was mentioned twice in ThoughtWorks Technology Radar, in 2013 and 2014, [ 2 ] "as a tool worth trying", [ 2 ] with an emphasis on "the interesting ...
Load testing tools are used for Software performance testing to create a Production-like workload on the System Under Test, and measure response times under this load. Pages in category "Load testing tools"
Performance measures include elapsed time of the test, the amount of data transferred (including headers), the response time of the server, its transaction rate, its throughput, its concurrency and the number of times it returned OK. These measures are quantified and reported at the end of each run. [4] This is a sample of siege output:
The second set of performance metrics measures the computational resources used by the application for the load, indicating whether there is adequate capacity to support the load, as well as possible locations of a performance bottleneck. Measurement of these quantities establishes an empirical performance baseline for the application. The ...
Load testing (stress/performance testing) a web server can be performed using automation/analysis tools such as: Apache JMeter, an open-source Java load testing tool; ApacheBench (or ab), a command line program bundled with Apache HTTP Server; Siege, an open-source web-server load testing and benchmarking tool; Wrk, an open-source C load ...
