I have a Dell Precision 490 workstation computer which I installed the latest version of Ubuntu Linux on. It has 8GB RAM, and Dual Xenon CPUs, so a total of four cores.
The problem is I give my VM machine, which is a Windows 7 Ultimate 4GB RAM, and 3 CPUs, and I receive poor network performance.
I made this machine because I wanted a Linux machine, and a Windows 7 machine which I can SFTP to, do some Apache PHP stuff, and also RDP to Windows and have access basically everywhere.
When I RDP to my machine it accepts my connection pretty slowly, and when I finally get in, I can only do easy tasks: browsing network shares with thumbnails takes forever, and if I accidentally open a webpage it takes a long time to refresh it just once.
What really takes the cake is that if I open MSN I basically just lose the connection and it tries to reconnect all the times. When I reconnect, I can see the screen drawing then stopping and I lose the connection again.
I have another computer which runs Windows 7 Ultimate on the same network. I run RDP on a different forwarded port, which has absolutely no issues on network performance, so what can I do in order to enhance the performance?
Here is a dump of uptime and TOP + various other stats if anyone can make anything out of it:
