I am noticing a weird network issue. Scenario is when I try to copy file from a host in site A to a host in site B file copy is very quick. But when I tried to copy a file from site B of the same host to site A of same host file copy is very slow. Both are windows network.
Site A host 1 ------copy-ï Site B host 2 Quick
Site A host 1 ï---copy --- Site B host 2 slow
Site A is connected to site B via 10Gig dark fibre link. The distance between site A to site B is approximately 7 kms. We are using Cisco 3750-E with 10Gig Zen-pack module between these two sites. I would like to know what causing this issue. The network is routed via EIGRP.
Please provide me with valuable guideline to identify the causes.
