    Okay, check out the new version with improved compression. Probably, this is the last version with super-fast decompression speed. I think next versions (5.2devX) will be similar to ROLZ3 - i.e. next versions will have really higher compression.



    And now, download TC 5.1dev3:

    I had hoped that this version would have super-high compression from the ROLZ engine. Please put the next version of TC in the top ten with a new super-high compression ROLZ engine.

    It depends on data type. On binary files the difference is small, but on text files and on big files the difference can be noticeable.

    I had hoped that this version would have super-high compression from the ROLZ engine.

    I've just started writing the new engine... Patience please.

    Please put the next version of TC in the top ten with a new super-high compression ROLZ engine.

    Step-by-step... The FPW like engine can achieve such high place. The ROLZ like - cannot. For example, try to compress each file from SFC with 7-Zip using same parameters, with 'Ultra' preset, for example, and look at results... Also you can try ROLZ2 or ROLZ3 from MComp...



    Anyway, this week I finally invent how to efficiently combine LZ like and PAQ like engines. PIMPLE was just a first shot... And from now on I will start creating a new engine, step-by-step. Also note, It's really hard-to-do. But it is possible and I can do this. Currently, I have a first prototype based on LZP and CM. The performance of this program is amazing. So, like I said, let's wait and see...

    But first of all, I'm very curious about performance of current TC on MFC and Squeeze Chart...

    Why tc5.1X so slower

    TC 5.0devX uses LZP. TC 5.1devX uses ROLZ. Note about TC 5.1dev3. The ROLZ like model in this version is more bigger and stronger. Unfortunately, decompression speed in TC 5.1dev3 is also slightly affected. Anyway, I know how to speed up the decompression (2x times faster or even more), since I've just invented how to increase decompression speed without any compression loss. Note, before, I know only how to increase this, but with some compression loss - that's why I not include a faster decompression in this version.



    About the future. Probably, within one week or two, I release a version with significantly faster decompression. Later, instead of writing new engine from scratch, I will add a PAQ inspired coder right into the current TC. And again, firstly I will add a fast version of this coder, and if compression will be lower than expected, I again increase it in some cost of speed...
