I broke down and purchased a DROBO 5N and populated it with 11 TB and a 256G cache. I attached it to a 1G switch in the Home Theater cabinet that goes to the ATV3 and a 1G router. The router goes to my PC running iTunes. The speed is about 500Mbs to the drobo. I still have a delay upon startup and am wondering what ideas people may have for minimizing the delay as much as possible. For example, I have an old PC laptop running XP. If I put that on the same switch in the Home Theater cabinet, will that make a substantial difference? What other ideas are out there?
