UDA 0.303.
Full disclosure: I have no formal programming or data compression education. I always liked UDA 0.301 and when I looked at the source code, it seemed fairly understandable...So I started playing around.
I released UDA 0.302 for benchmarking purposes only for the SqueezeChart. After seeing the improvement in compression ratio and some interest from members on this forum, I decided to keep playing around.
UDA 0.303, unlike all previous releases, has 3 version:
MAX
This one is tuned for absolute maximum compression ratio-speed is not important. This version should have a better compression ratio than 0.302.
FAST
The goal of this version is to achieve almost identical compression ratios as UDA 0.301 released by dwing almost 10 years ago by increasing the memory usage and making other modifications to the code.
VERYFAST
This is the speed king! The goal was to achieve the fastest possible speeds while still keeping a good compression ratio. Some modifications to the source code would increase the speed by 200% but compression ratio would drop by 200% also-so that was unacceptable.
All versions require 2GB memory and are 32-bit Windows executables compiled with the fastest possible settings using Intel C++ 11.1 compiler.
Looking forward to seeing benchmark results and hearing opinions!
