Routed Networking Slowdown on Proxmox 3

Hey folks,

Got a problem with our proxmox server running on a dell r720. We are running proxmox 3.0-23-957f0862

Our setup is the kvm routed configuration where we have several vmbrxx interfaces which are applied depending on what network we want the VM to be on and use static routes to those networks on our main router with ip forwarding on the proxmox server to route to the vmbr networks.

I currently have issue where ssh works fine to vms however if I try and run scp or rsync the transfer rate seems to start high and then slow down quickly until it stalls. What could be going on!

Network Config - /etc/network/interfaces
Code:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
        address  192.168.250.22
        netmask  255.255.255.0
        gateway  192.168.250.234


auto vmbr0
iface vmbr0 inet static
        address  192.168.151.1
        netmask  255.255.255.0
        bridge_ports none
        bridge_stp off
        bridge_fd 0


auto vmbr1
iface vmbr1 inet static
        address  192.168.152.1
        netmask  255.255.255.0
        bridge_ports none
        bridge_stp off
        bridge_fd 0


/etc/sysctl.conf
Code:
# Uncomment the next two lines to enable Spoof protection (reverse-path filter)
# Turn on Source Address Verification in all interfaces to
# prevent some spoofing attacks
net.ipv4.conf.default.rp_filter=0
net.ipv4.conf.all.rp_filter=0

# Uncomment the next line to enable packet forwarding for IPv4
net.ipv4.ip_forward=1
