maximumcompression.com lives!!

[Rugxulo]

I just randomly checked here, and guess what? IT LIVES!!!

23-December-2009 : Added FreeArc 0.60, WinRAR 3.91, 7-ZIP 9.10, NanoZip 0.07a, UPX 3.04, BCM 0.10, Packet 0.91b, CSC 3.1, RINGS 1.6, LZTurbo 0.95, QPress 0.38b, FlashZIP 0.99b5, BWMonstr 0.02 (MFC todo) and LZP2. FreeArc keeps improving as version 0.60 shows improved compression speed (and in some cases even improved compression ratio) compared to the 0.51 version. FreeArc again sets a new performance record in the efficiency ranking!. WinRAR also made a big jump in efficiency as compression speed was greatly improved by adding better multi-core support (introduced in WinRAR 3.90). It now takes a clear 3th place in efficiency ranking, behind FreeARC and NanoZIP. LZP2 fails to qualify for listing in the MFC charts as the compressed filesize produced by LZP2 is too big (> 1/2 org size).

P.S. Merry Christmas to everyone!!

Yeah, I'm glad to see the site is alive.

Yeah... updated:

6-July-2010 : Added FreeArc 0.666, NanoZip 0.08a, 7-ZIP 9.15, PackJPG 2.4, Etincelle RC2, YZX 0.04, BSC 2.2.5, UPX 3.05, BCM 0.11 and CSC 3.2a6. PackJPG 2.4 takes 3th place in the JPEG compression test. As expected, the new versions of both FreeARC and NanoZip keep fighting for the top places in the most efficient compressor ranking. from WinZip.

Updates!

28-November-2011 : Added SCM 0.0.1b, XP v5 and Crush 0.01. SCM is a good compressor, but is still buggy (e.g. crashes on JPG file with -o option) and options given seem to have no effect on compression level.

19-November-2011 : Added WinRAR 4.1b3, 7-zip 9.25a, NanoZip 0.09a, BSC 3.0.0, Comprox 0.3.0 and PackJPG 2.5. Because of further multi-threading optimizations, Nanozip in default mode, makes a nice jump in compression efficiency and closes the gap to number one, FreeARC. Comprox crashes on the PDF file when using a blocksize < 5 MB and crashed on the MFC test when using a blocksize < 17 MB

the -o option does currently not work. all options are accessed through "profile.txt". Select memhash=29, and counter_sse=1 for maximum compression...maybe then SCM will be slowest compressor in the world

Good to see maximumcompression.com is not dead, but guestbook doesn't seem to work still.

Historic data seems to be gone...
