httperf need the "=" for it's args. Otherwize it is just ignore.
I have test it with port for instance. It work with the patch, and not without.
Fix passing args to httperf
Hmm, did they change this recently? Because it certainly worked without the ='s before. What platform are you on?
I use ubuntu quantal (12.10)
the httperf ship with it has somehow change their way to handle params.
