new.gif (1134 bytes) WebStone 2.5

We've just released WebStone 2.5. Both executable and source code are available for free and will stay that way. The highlights of the new release are:

  • It's much more reliable.
  • Tests are reproducible. The previous version of WebStone used a time of day random seed. Now it can optionally use a fixed random seed.
  • WebStone 2.5 comes with a new license designed to encourage you to contribute enhancements while protecting you and your company from liability.
  • There is an optional new dynamic workload that simulates ad rotation.
  • WebStone 2.5 results can be compared to WebStone 2.01 results (unless you use the new dynamic workload).

Future Enhancements

Mindcraft wants to encourage the WebStone community to make enhancements for everyone to use. The most popular WebStone enhancement requests are:

  • SSL support
  • POST support
  • HTTP 1.1 support
  • Cookie support
  • Dynamic workloads with database access
  • Authentication
  • HTTP 1.0 keep-alive support
  • The ability to send different headers
  • Support for a large number of URLs
  • Pre-compiled executables for more systems

Please let us know if you are interested in contributing code to the WebStone community in these or other areas.

Mindcraft will freely redistribute contributed WebStone enhancements.
