It's extremely unlikely you'll be able to saturate a 10g link with a single instance cassandra. Faster Cassandra streaming is a work in progress - being able to send more than one file at a time is probably the most obvious area for improvement, and being able to better deal with the CPU / garbage generated on the receiving side is just behind that. You'll likely be able to stream 10-15 MB/s per sending server or cpu core, whichever is less (in a vnode setup, you'll be cpu bound - in a single-token setup, you'll be stream bound).
