How much slower is booting with ubuntu from a USB stick vs. installing it?

Way too much slower to bother with? and when I say "booting," I guess I am including actually operating the OS, as well.

I can't say but a usb stick is solid state so I don't see why it would be slow.

It is actually very slow running from a USB stick. From my experience the OS and programs load at least twice as fast from even a platter drive than from a USB stick.

Just to put some real numbers behind it, USB sticks usually benchmark at less than 10MB/sec, while HDD's typically do 50+MB/sec, and many SSD's do 250+MB/sec.
So the jump from booting from a USB to a HDD will be about as significant as going from HDD to SSD.

Gotcha. Is the transfer speed an issue because of the lack of power?

It's the bottleneck of USB 2.0.
Edit: and to expand on that, SSDs and USB flash drives are not comparable. While they are both NAND-based, the SSDs are superior because of their more sophisticated controllers, parallel NAND, and (in some models) DRAM cache.
