Hello, I've been running some benchmarks on UML instances running inside Amazon EC2 instances. Specifically, I've been running the Ruby on Rails test suite. My experience so far shows the UML instance to be running between 5 and 10 times slower than running on the bare EC2 instance.
I know that some performance loss is inevitable with virtualization. My question is, is this a typical level of performance degradation? Given the right tweaks, how close to native speed can I expect to get UML performance? Some parameters: I'm running instances with 256MB RAM. Upping the memory to 512MB did not improve performance. The benchmarks were done using a raw file as ubd0, no hostfs or humfs. Because I'm running under EC2 and have to use their kernels, there's no chance of using SKAS3. I just want to get a idea if my numbers are roughly similar to others' experience, and if it's worth my while to explore optimisations.
