- Hide the request output unless user asks to see it
- display a running percent complete when -q is selected
- Add support for user-defined delay, and random delay to simulate more realistic workloads
- Allow password auth
- Allow reading users/passwords in from a file, and allow to sort them and use them in order when generating requests
- Allow a mode where the user specifies a target requests/second, and attempt to reach that target? radperf does this somehow...
- Allow specifying test run time instead of # of iterations
