Sorry if theme is offtopic.
I need file generator with adjustable entropy level to test LZ-based algorithms.
All generators i've found generate null-filled (highly compressed) or random (uncompressed) data. There is http://cs.fit.edu/~mmahoney/compression/uiq/ too, and files, generated with it are compressed with Deflate at ~1.6 ratio. But entropy level of UIQ is not adjustable and it it very slow - 3 mb\sec at best, i need at least 20 mb\sec.
Does anyone know about such an utility? I'll be very pleased to have a copy Thanks.
