注:
1.表格中绿色项的压缩软件是本站推荐的压缩工具.(The green items are recommanded.)
2.本测试的目的不只在于压缩率,还考虑到压缩时间和内存占用,内存限制在256MB内.(The aim of the test is for {Compression Ratio/Time}. Memory is limited in 256M.)
3.MP3,WMA,WMV,AVI,RM(VB),RA,JPG,GIF,PNG,CHM等格式的文件虽常见,但由于这些类型文件已经经过压缩,数据冗余度很低,因此再压缩无意义.(These types of files are not compressable.)
4.只能压缩单个文件的压缩软件不在测试范围内,其中包括:Ocamyd,EPM,RKC,UHBC,ASH.(These compressors can deal with only one file.)
5.其它经过测试但压缩率时间比太小并且很不常见的压缩软件没有列出,其中包括:BEE,CTXf.(The compression ratio of these compressors I tested are too bad and useless.)
6.关于解压速度:RAR,ZIP,7-ZIP解压速度明显高于压缩速度,而且7-ZIP的解压时所需的内存比压缩时也减了不少,Durilca的解压速度是压缩的3/4,其他软件压缩与解压缩速度几乎相同.
7.测试电脑配置(Computer for test):AthlonXP1600+,KT266A,384M DDR266-SDRAM,WindowsXP(SP2)
8.测试文件(Files for test):
user32.dll(547K,one system file of WindowsXP)
control.doc(531K,a file of Word,english text with picture)
world95.txt(528K,partial english text from www.maximumcompression.com)

注:
1.由于压缩速度与前一测试相同,所以此表省略了压缩时间统计.
2.SLIM,DURILCA不支持固实压缩,因此在此测试中很失利.(SLIM and DURILCA seem not support solid mode, so their compression ratio is worse.)
3.SLIM,DURILCA对常见格式文档的压缩进行了优化,所以对于一般数据的压缩要差一些.(SLIM and DURILCA have filters of common file type, so their compression ratio of other data is worse.)
