than specified dictionary size.
7-Zip now can use large memory pages:
GUI: 7-Zip File Manager / Options / Settings / Use large memory pages.
Command line version: -slp switch.
This feature allows to increase speed of compressing. But 7-Zip can make
some pause at starting of compressing for allocating large pages. Also
Task Manager doesn't show real memory usage of program, if 7-Zip uses
large pages. This feature works only on Windows 2003 / XP x64 / Vista.
Also you must have administrator's rights for your system. Recommended
size of RAM: 1 GB or more. To install this feature you must run 7-Zip
File Manager at least once, close it and reboot system.
