WebThe -m700 option selects 700 MB of memory. (It appears to use substantially more for enwik9 according to Windows task manager). -o12 selects PPM order 12 (optimal for enwik9 -t0). -t0 (default) turns off text modeling, which hurts compression but is necessary to compress enwik9 (although decompression still crashes).
