Use large memory pages
If enabled, 7-Zip will try to use large pages. This feature
allows an increase in speed of compression. This may cause 7-Zip to
pause when starting compression, because of allocation of the large
pages. Also, the Windows Task Manager doesn't show the real memory
usage of the program, if 7-Zip uses large pages. This feature works
only on Windows 2003 / XP x64. 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 the system.
