The program website describes the archiver in the following way:

CTX is a file archiver which uses advanced contextual modelling techniques combined with multiple optimization tricks. This helps CTX to achieve superb compression rates on typical data, such as texts, executables, waves, pictures, JPEG & MPEG files, office documents, etc.

CTX core has a lot of settings which can be used to adjust compression/speed level. In fact, it is one of the fastest universal contextual compressors.
