There are two things that come to my mind. First, do you really need to 
use all those data? I would bet that a sample of say 1e5 from each list 
item would give essentially the same picture.

Alternatively, you might consider using a bitmapped graphic rather than 
a vector graphic. I am assuming here that you have lots of outlier 
points (outside the whiskers) that are slowing things down. You could 
use a png, and as long as you aren't resizing it should look OK.

Best,

Jim
