It is hard to compare compression savings without specifying the data set used.The Silesia or Calgary corpus could be used as the reference set. Both the compressibility ratio and the compression performance is highly data content dependent.

I see only relatively small compression gains so the content must be 
partially compressed already, or does not compress well.

Lzma type compression (e.g from xz, lzip, or 7z) will do better than 
zip for this purpose.
