Note to self, when testing backup software that needs a gigabit link to get full performance, use the gigabit card for the network connection, not the 100 Mbit/s card. I’ve been doing speed tests to test the multiplexing of Yosemite’s Backup, and it was capping out at 600 – 650 MB/minute, even with 8 servers as clients. Two days into the testing, I realise that I forgot to move the appropriate IP to the gigabit fibre link. Did that just now, and the backup server is pulling data in at 1.1 GB/minute or more.
