Review on WebLOAD by Marc Gallner

The ease to use, multiple options for tests types (iostats/netstats), ability to run concurrent jobs as well as long running ones without having any issues.

There are some features which could be improved but nothing majorly negative about this software so far - I think it has been great! You can easily get into trouble when you have too many users connected or your server becomes overloaded from all those connections / requests coming throughtout day. We've used webload loads our servers up during peak times by simulating real user behaviour using virtual machines instead of actual computers.
