I've installed Ubuntu Server 10.04 (64 bit) on a Hyper-V Server R2. I've encountered two issues that I think are related:
- Very slow install
- Very slow command prompt
The text-mode installer goes through a series of text-based prompt windows. It takes 7-10 seconds for each of these windows to draw on the screen. The end result is that every time I answer a prompt and hit enter I wait for 15 seconds while the screen redraws line by line. I can literally see each line of text being drawn (like the old 300 baud modems days).
Once done installing, scrolling on the command line is super slow. For instance, if a simple command, like "ls", causes the screen to scroll, it will scroll very slowly.
This happens on a fresh install. The server functions as a LAMP server and an OpenSSH server, but that's it (I don't even have any Virtual Hosts set up yet). AND this only happens on the Virtual Machine console. I access the console through Hyper-V Manager and don't have this problem on any of my other Virtual Machines.
Also, this problem does NOT happen when accessing a shell through OpenSSH.
How can I improve this performance issue?
