    Why is it so slow?

Because drawing wide-line arcs is hard to do fast while matching the
protocol specification, and there is no optimization for thin-line
arcs in the R3 server.  Fast thin-line arc code will exist in R4.

    Can you give me a pointer to the code that does the actual drawing?

server/ddx/mi/miarc.c, if you are really want to get depressed.
