Emulator Performances


1- Which freeware or open source emulator application is the fastest?
QEMU? Xen? VMWare? VirtualBox? ...

2- Does the host OS's abilities and performance affect the emulator's abilities and performance?

for example, if host OS does not have USB support, can emulator app. provide USB support to guests? (I know it sounds absurd, but it came into my mind

3- Will there be a speed difference if I run QEMU or another emulator under tiny sized distros like DSL, Puppy vs bigger distros like Ubuntu, Fedora, Slackware...?

Many thanks for your opinions and valuable help.

If what you want to do is to run windows applications, then the fastest emulator is by far Wine.
If you are emulating another processor or another OS, the results might be very different. It depends on a lot of factors actually.
What are your machine specs (RAM, processor, disks...)?

My laptop specs :
An Intel dual core 2.0 GHz CPU (T7200) with a 2 GB RAM.

I'm using Windows XP right now, but the emulator performance question is generic, I'm planning to use it on Linux.

At an ordinary worktime, min. 1 GB of RAM is used (currently 1.2 GB used with 3 apps working at front!)
HD is a little slow one, and disk space is rather limited, less than 10 GB left free

I plan to use emulator on both cases :
Linux on Linux.
Windows on Linux.

Performance-wise I believe Xen is the fastest Linux on Linux emulator due to paravirtualization support. (VMware workstation also has this option, but it's not free)

Anyway, here's a good comparison table:
