edit: Yes, chroot isn't emulation. Its an independant runtime environment. However, due to the way its composed it runs above the Android system. So it does get hit by performance issues, despite whatever anyone says. Surely not as bad as actual emulation, but its far from the 'nix on desktop. I don't think it runs faster than Dalvik, actually it runs slower. Here's an illustration, think of chroot "running natively" on the blue section... far removed from the system. I haven't even touched on the delay you get from loading this on a microSD card which are slower than NAND/SSD on devices. Or the fact that the information relays both ways, so that delay is multiplied twice. Have I confused you yet? Yeah, so its not really far removed from emulation when I refer it as emulation (and I'll continue to say so to point out how inferior this approach is compared to a native installation).
