So I am also sending this to both the pstricks and the powerdot lists as it relates to both, but mostly to compiling via dvi-> dvips -< ps2pdf or similar.
I make my lecture slides with Powerdot and use pstricks a lot to create arrows, circles, diagrams and so on. But I also include eps figures, some on which I operate with pstricks.
The problem is that some of my eps files (such as from Mathematica or ones I have converted my jpg with lots of resolution are very large ( 50--60 mb)
This then makes the latex compiling take forever.
I sometimes use an include statement so I can % out the worst of these slides except on final compilation, but this get annoying,
Anyway to precompile some of this stuff so that the final compile takes less time,
