mrk is a modern HTTP benchmarking tool written in C++17 it is capable of generating a significant amount of load when executed on a single multi-core CPU.

the tool is compatible with both Windows and Linux operating systems

mrk is based on wrk, although it does not currently achieve the same level of performance.

• support OpenSSL 3.0 to enable secure HTTPS connections
• improve overall performance
• Address a bug that occurs during the testing of a server with limited file descriptors (fds)
• add more command line options
• support lua scripts

  mrk -t10 -c500 -d60s https://localhost:8888

This runs a benchmark for 60 seconds, using 10 threads, and keeping 600 HTTP connections open.

Output test Orpy on Linux:

On Linux:

  mkdir build & cd build
  cmake ..
  make  

On Windows create a build folder and open a command line in it:

  cmake ..

Open .sln file created with Visual Studio

  -c, --connections: total number of HTTP connections to keep open with
                     each thread handling N = connections/threads

  -d, --duration:    duration of the test, e.g. 2s, 2m, 2h

  -t, --threads:     total number of threads to use
