PerfView
PerfView is a CPU and memory performance-analysis tool
PerfView is a free performance analysis tool that helps isolate CPU and memory-related performance issues. It is a Windows tool, but it also has some support for analyzing data collected on Linux machines. It works for a wide variety of scenarios, but has a number of special features for investigating performance issues in code written for the .NET runtime. If you are unfamiliar with PerfView, there are PerfView video tutorials. -

LoopVectorization.jl
Macro(s) for vectorizing loops
LoopVectorization.jl is a Julia package for accelerating numerical loops by automatically applying SIMD (Single Instruction, Multiple Data) vectorization and other low-level optimizations. It analyzes loops and generates highly efficient code that leverages CPU vector instructions, making it ideal for performance-critical computing in fields such as scientific computing, signal processing, and machine learning. -

OpenResty SystemTap Toolkit
Real-time analysis and diagnostics tools for OpenResty
...It provides developers and system administrators with tools to trace performance bottlenecks, memory usage, request distribution, regex execution, Lua execution, and file I/O behaviors in production systems. The toolkit helps identify leaks, analyze TCP queues, inspect shared memory usage, and generate flame graphs for CPU and off-CPU profiling. Many scripts are specific to NGINX worker and master processes, while others are generic enough to be applied to any Linux user-space process. Although the toolkit is no longer actively maintained—development has shifted to OpenResty XRay—it remains a valuable set of examples and utilities for advanced users of OpenResty and NGINX. -

sysbench
Scriptable database and system performance benchmark
sysbench is a scriptable multi-threaded benchmark tool based on LuaJIT. It is most frequently used for database benchmarks, but can also be used to create arbitrarily complex workloads that do not involve a database server. extensive statistics about rate and latency is available, including latency percentiles and histograms. Low overhead even with thousands of concurrent threads. sysbench is capable of generating and tracking hundreds of millions of events per second. New benchmarks can be... -

cpuplot
Command Line profiler of CPU usage
cpuplot Command Line Profiler of CPU Usage and Load Average. Synopsis: BASH script that shows the history of CPU usage, and what procces uses the most CPU at a given time. Bar graphs represent the percentage of Total CPU Usage, and the percentage of Total 1 Minute Load Average. Default wait interval between system readings is 5secs. But a different one can be set in the command line with the "-i" argument. -

TCPCopy
An online request replication tool, also a tcp stream replay tool
...To support more realistic testing of Internet server applications, we develop a live flow reproduction tool - TCPCopy, which could generate the test workload that is similar to the production workload. Currently, TCPCopy has been widely used by companies in China. TCPCopy has little influence on the production system except occupying additional CPU, memory and bandwidth. Moreover, the reproduced workload is similar to the production workload in request diversity, network latency and resource occupation. TCPCopy consists of two parts, TCPCopy and intercept. While TCPCopyruns on the online server and captures the online requests, intercept runs on the assistant server and does some assistant work, such as passing response info to TCPCopy. -

SarBox
SarBox helps user to parse or analyze sar data
...SAR is cumulative activity counters in the operating system. It is the most comprehensive command which helps to monitor performance of various Linux / Solaris subsystems (CPU, Memory, I/O, Disk, Network, etc) all in same log. This makes it difficult to analyze since every counter data is dumped into the log file. SarBox helps to analyze this log file and present data in graphical charts or text format. To collect sar statistics from an environment, use below syntax [user@host ~]# sar -A 30 2 > sar_linux.log “30 2” reports for every 30 seconds and total of 2 times, written in sar_linux.log. -
