So beside the fact that TLS as a cpu cost, LZ4 depending of the type of data too. I would go for a run without LZ4 first to see how much cpu bonding is your FD.
Then you may want to tune TLS to only use cipher that may benefit hardware acceleration like certain aes. Trying without TLS will give you a better view of how much % it cost. You may then want to consider ktls https://docs.bareos.org/TasksAndConcepts/TransportEncryption.html#enabling-ktls The global bytes/sec seens at the end is really a "naive" computation between the time spend between how much data divided by stop-start timestamp. If you're loading tape (the time to load, unload is included), if the job is waiting 1 hour an operator to label a volume, that also count. so so ...
