Hi, I have been tracking this thread because I too have this problem. I'm using an Ubuntu 9.4 twin Athlon 1.6 CPU. with 1GB RAM. I'm using the Linux x86 build, so this may be part of the issue? If I were to build it myself perhaps the problem would go away? It takes at least 3 minutes to start the emulator. To run an Android app from Eclipse on the emulator takes about the same. It is much too slow. There is something wrong. I suspect some kind of busy/wait issue or other timeout issue. There seems to be very little churn on this topic, so I can only assume it is not biting everyone. Several of my work colleagues noticed the same thing on their Ubuntu systems at home. At work we use Mac's and everything is ok. A little sluggish, but acceptable.
I have an answer for David Turner: using the -no-audio flag doesn't change anything! I suspect that some AVD parameter or whatever is set too low. Does the emulator have enough stack etc to run in on Linux? Is the cpu-delay somehow being set to some unwanted default?
