I need some advice with regards to poor network performance over WAN. Following scenario:
As part of an outsourcing strategy, around 100 contractors in Hyderabad/India are required to access their assigned VM (Windows XP) hosted at the HQ in Brisbane/Australia. The WAN is a 2Mbps dedicated leased line using Cisco routers (Gt96k FE). The contractors have complained about slow network and application performance.
Our network department looked into this issue and compiled the below attached output taken from the Cisco routers and advised that the WAN connection is fully operational.
Our server team monitored system performance of 3 most affected VM's over the past month with the following results:
- CPU Usage (Average/Rate): 2.23%
- Disk Usage (Average/Rate): 22.82KBps
- Memory Usage (Average/Absolute): 4.75%
- Network Usage (Average/Rate): 1.61KBps
To me, it looks like the WAN connection of 2MBps is not in proportion to the required bandwidth. There are currently 98 VM's utilising a bandwidth of approx. 50KBps per RDP session. Doing some math: 98 VM's * 50KBps = 4,900KBps.
Thanks and regards,
