Each file is compressed into compressor's name on greenish-yellowish background in italics = newly added into the table
separate archive bold black numbers on yellow background = the best result in this column
bold black numbers in italics = the worst result
red numbers (bold in italics)= compressed file is the same or even bigger size than original file (and the worst result)
Thanks to following people gray background = archiver couldn't be run in best mode (mostly due to RAM limiations)
for their contribution: 1 means Precomp 0.3.1 (fast mode) + DURILCA'LIGHT 0.5 (only -m1500 -t1 switches used, no results tuning)
2TXT1, TXT2, DLL and PNG were tested with -m switch up to 1800, rest using -m switch up to 700
- LovePimple 3KZIP doesn't decompress by itself, 7-zip 4.42 was used for decompression
- encode 4 QuickLZ compressor family (de)compresses so fast that it is hardware what really limits (de)compression speed.
- Idris Kubatayev 64 Compressor has been tested under 64-bit Windows.
- Fallon CRASH = compressor crashed or freezed during compression
- Christian Martelock FAILED = run-time compressed exe couldn't be run / (de)compressed file was corrupted
   Notes: These results may not be the best results for each used compressor. However, I have not found any better combination of parameters.
         Each compressor is tested for maximum compression, NOT for speed.
         All compressors are tested in 32-bit Windows, if not stated else.
         Test files are not available online.
         (De)Compression times measured via Timer 3.01 by Igor Pavlov (global/wall time).
         Decompression speed = (uncompressed size / decompression time)
   Testing set: Athlon 64 X2 3800+, for some tests 2GB RAM (~1800MB free), for other 1GB RAM (~700MB free), SATA HDD
  I have also tested but didn't include:
   WRT4.6 (it's built into PAQ compressor)
   LHA 2.67 (it is old (1995) - 18 169 390 bytes  - speed about 5000)
   ASD 0.1.5 (it is old (1997)- ~19 000 000 bytes - speed about 6000)
   QuArk 1.0beta (it is old (1995) - 18 174 076 bytes - speed about 3200)
   DC 0.98b (fails to run)
   ArchonX3 (it's built into Dark compressor)
   Chaos Compressor 3.0 (fails to run)
