RE: Slow upload download on storage network
You may want to focus on SSVM; either isolate or rule it out as a cause. You could do a wget from within the SSVM and see what throughput you get. Check if there is QoS set on the SSVM's storage interface. Check CPU/RAM, Rx/Tx and disk I/O.

On one linux vm which was on xenserver host, I just added one more interface of storage network NIC. And mounted nfs on it. Downloaded iso from storage network on nfs mount point. Same 4GB iso download was done in 8mins. What do you think could be problem? I am using Xenserver 6.2 and bandwidth I have on storage network is 1000Mbit/s.

Try mounting the secondary storage NFS share on a Linux box and check the network performance when you copy a similar sized file. What throughput do you get?

When I download any iso, like just 4GB iso takes 4-5 Hrs. It's so weird. My secondary storage in nfs. I felt since SSVM is mounting the secondary storage mount on ssvm and downloading iso from there. That could be cause of slow network. So I even changed service offering for SSVM, and gave more memory and cpu, it's still same. I have configured Storage network for secondary storage traffic. So I am wondering what could be problem, since there is dedicated nic on nfs server and xenserver host, so it should just work. I am running CS 4.4.2 . Thanks, /Sonali
