Eclipse uses a lot of RAM. Minimum 1 GB, possibly 2 GB is needed.
If you have too little RAM you would obviously be swapping = SLOW.

We are using a low cost ($1 to $2) USB/LCD uC for a customer. Before
committing to several thousand masked ROM dice, they want us to
simulate all the codes. Simulating the LCD function is not a
problem. Simulating the USB 2.0 device controller would not be easy,
especially under Windows.
