The answer to your question is....it depends. Because the Blaze protocol transmits a completely different way than RDP different things will affect the performance.
The Blaze protocol works best in an evironment with bandwith restrictions or latency issues. This means that on a standard LAN connection the difference between Blaze and RDP is not that much. However, on a WAN or internet connect, the Blaze protocol may be much faster.
My best recommendation is download Ericom Blaze and install in your environment. You can trial it for 30 days and compare the difference on your actual network.
