I agree that you should do data-specific compression first, and then
maybe use a general compressor to further compress the result before
transmission.

Of course Zlib is the most widely used compression library out there,
but if speed is important to you, you can take a look at UCL and LZO.
http://www.oberhumer.com/opensource/ucl/
http://www.oberhumer.com/opensource/lzo/

These are two libraries designed by the guys who make UPX. Overall, I
would say that the compression ratio and speed of UCL is great (I feel
it has a better compression than zlib, and it is quite faster, but I've
never done a real benchmark.) The other algorithm, LZO is a bit faster
but makes a bit larger data.

Both libraries are under GPL though. I don't know whether that is good
or bad for you.
