Great! about performance: I tried to tweak a lot of parameters, but what I found has most influence on the throughput on the reading side seems to be "receive.buffer.bytes". The optimum varies depending on your image size and other factors, but you can try to do a bit of parameter search. In my case this seems to be the best. Also, if it is acceptable to your application, using autocommit speeds this up quite a bit, but you must accept a bit of uncertainty as to when you commit an offset.
