я лично никаких сложностей не вижу. файлы объединяются в солид-блоки для улучшения сжатия. затем блоки разбиваются на куски фиксированного размера для ускорения работы :) -mmt2 даст тебе один кусок для -mx5 и выше, и много кусков при -mx3 и ниже. во всяком случае так было раньше, сейчас может изменилось :)
chunk==кусок. lzma2 может разбивать сжимаемые данные на отдельные части, и сжимает их независимо, в параллельных потоках. новая версия умеет и распаковывать параллельно несколько кусков. замечу, что и при упаковке и при распаковке эти куски должны принадлежать одному solid-блоку
chunk==кусок
Igor, please look at discussion around http://forum.ru-board.com/topic.cgi?forum=5&topic=49016&start=380#18 and especially document provided in this post. Unfortunately, it's in Russian, but in short - since there are lot of new codecs/formats around, and 7z got their support, in particular via 7zip ZS project, next step may be a standard API that will allow 3rd-arty GUIs to present to users codec parameters such as dictsize or clevel, so they can choose compression settings.
