Compression dictionaries give a good compression ratio (~50%) and also increase TPS a bit (5-10%) due to better buffer cache utilization. At least according to synthetic and not trustworthy benchmarks I did some years ago [1]. The result may be very dependent on the actual data of course, not to mention particular implementation of the idea.
