I'd reckon that is not completely true. A lot of switches, just to reach to their customers quickly, implement openflow in software. That means, openflow actions and everything are implemented in software and no specialized ASICs are added to implement the functionality. This of course obstructs line rate and the performance is observably slower than the ones that implement openflow in hardware.
An example is, you have a flow entry that rewrites IP addresses for every packet that matches the criteria. This, if done with hardware will give you line rate performance. But if done in software, will make it noticeably slower. Please correct if I'm wrong.
