download speed

Linux --> Inside-if CSR1000v --> NAT --> Outside-if CSR1000v --> Internet Cloud == Low speed :(
Linux --> Inside-if IOSvL3--> NAT --> Outside-if IOSvL3 --> Internet Cloud == Low speed :(
Linux --> Inside-if Dynamips 3725 --> NAT --> Dynamips-if 3725 --> Internet Cloud == Low speed :(
Linux --> Internet Cloud == High Internet Speed :D
I tested IOL 15.5.2, it gives me full speed.


vIOS is slowest
CSRv1000 need license to have full speed
IOL is fastest
Dynamips is too old.

feature

iosxrv 6.6.2 image does not support
bundle load-balancing hash src-ip
Rest is fine
