You're only talking about the client. What about:
a) Extra time in the sprintf in the planet dumper, on the server
b) Extra time to compress the result, on the server
c) Extra time storing said data on disk, on the server
d) Extra time transferring it over the network to your machine, from the server

When you add all these to your option b, the current setup doesn't
look so bad anymore... Especially since 99% of people will never use

Have a nice day,
