Yes, a fair bit faster...

I'm actually going to be using this for paste, and will be typically 
doing manual pick&place (aka tweezers).  As long as it can squirt paste 
faster than we can hand pick&place, we're golden.   Actually, it looks 
like it's about twice as fast as the placing step, so it should be able 
to keep up with two people doing p&p.

Remember, with p&p you really need fast rapids...  That is, go between 
the component source and the position on the board a lot of times (with 
possibly some vision and/or centering step).   With paste, it's more 
touch every spot on the board which needs paste, so the speed of the 
machine plays a factor, but not nearly as much as in a p&p machine since 
the overall distance needed to touch all of the pads on the board is 
significantly shorter than to touch all of the component locations on 
the board with a trip home between each one.
