Meeting Notes:
- 'Endurance testing' - testing at load for a long period of time to surface problems like memory leaks, etc
- Can be useful to use the term 'emulation' and not 'simulation' when describing load testing that's hitting production servers
- 90% of current load testing is web load testing
- Need to consider much besides planning for results data for load testing - need a team effort to analyze results, plan use cases,
tune system, set up test/prod environments, server side monitoring and metrics, etc
- Often best to focus on a few simple scripts initially in a load testing effort, even just a login
- Useful to consider for load testing demo purposes: run simple manual GUI tests while load testing is underway
- MicroFocus, which last year took ownership of the Borland line of automated test tools,
is the vendor for the SilkPerformer load testing tool;

is the download link for SilkPerformer.
