Qemu is capable of full emulation, but when host & guest architecture  
match (or are compatible, e.g. x86_32 guest and x86_64 host) it's a  
virtualizer. Given x86 on x86, there is a world of difference between  
Bochs's performance and Qemu's.

Qemu's display is slow, whatever other factors exist. Drawterm to a  
qemu cpu server is very much faster. I can't speak for disk IO except  
to say it seems fast under my light usage.

Also, to nit-pick, don't all virtualisers emulate peripheral hardware?
