This is a list of performance analysis tools for use in software development.

General purpose, language independent[edit]

The following tools work based on log files that can be generated from various systems.

  • TimeToPic visualizes a log file. If system has logging facility, its output can be shown on visual timeline. Developer can see from visualization what is happening on log. Can be used for code and "logic" level analysis. There are version for Windows and Linux. Supports log sizes up to 1 Gigabyte.
  • time (Unix) - can be used to determine the run time of a program, separately counting user time vs. system time, and CPU time vs. clock time.[1]

Multiple languages[edit]

The following tools work for multiple languages or binaries.
