1GB's BMP compression test:
Code:
Original archive: bmp.arc (244,937,914 byte)
Methods: lzma:192mb:normal:bt4:128:lc8
Packed from grzip (with -mgrzip:256mb:h15:l2048:a):
Code:
5,483 files, 1,069,598,818 bytes, 320,784,780 compressed (not solid!)
tempfile+grzip..: 1,069,598,818 bytes, 321,101,123 compressed (solid!)
Packed from DLZ: 239,147,583 byte, Methods: -slp -d64m -lc8 -lp0 -fb337 -mc8192
Packed from bliz:
Code:
100m bytes dict. size: 258,506,104 byte
with 4096kB Dict size: 270,019,193 byte
tempfile+mm+bliz: 279,418,278 byte
mm+tempfile+bliz: 289,750,196 byte (not solid archive!)
Packed from MSC (BMF 2.0.1 with slow mode, bmf=9s)
VERYSLOW:
Code:
Compressed 5,483 files, 1,069,598,818 => 340,840,020 bytes. Ratio 31.87%
Compression time: cpu 108.97 sec/real 17445.55 sec = 1%. Speed 0.06 mB/s
BMF Results:
Code:
<--------------------------- B M P ---------------------------->
Total founded BMP: 4549
BMP with not supported header value "bit_per_pixel": 0
BMP with not supported line size (should be line_size_bytes mod 4 = 0): 132
BMP filtered by size: 0
processed BMP: 4417 (919'082'710 bytes)
Packed again the MSC/BMF-packed previous archive:
Code:
7z/LZMA: 232 253 503 byte
DLZ only: 228 604 204 byte
Note: DLZ its finished in ~41 mins from compression. BLIZ its faster.
and any compressors:
RAZOR 1.03.7 x64 with 512m Dict. size: 195 443 238 byte
LOLZ v22c4b (Brute detect disabled!):
Code:
default lolz settings (ldmf1, 64MB dict ...): 187,784,213 byte
lolz:dt:mtt1:mt4:d160m:fba4096:tt16:mc1023 -> 187,109,257 byte
All compression tests, except RZ/LOLZ use only from very old x86 PC with 1GB RAM. RZ/LOLZ used x64 laptop with 8GB RAM.
