WinRAR 4.20 Final x86 + x64 Pre-Registered [EC]

Winrar 4.20 (32bit And 64bit) Pre Activated - [EC]



**********************************************************************************



Whats New In v 4.20 ?



**********************************************************************************



general compression algorithm is optimized for better



utilization of several processor cores. While some speed gain



is possible even in single processor mode, best results



are achieved in multi-core environment



**********************************************************************************



Speed gain depends on data type and average file size



Several cores are utilized more efficiently when compressing



large files



b) we had to increase memory requirements to achieve higher



compression speed. General RAR compression algorithm allocates



about 120 MB comparing to 40 MB in WinRAR 4.11;



c) RAR text compression algorithm cannot utilize several CPU cores



efficiently, so its performance in multiprocessor environment



is much lower than for general algorithm. Also its decompression



speed is much lower than in general algorithm regardless of



CPU number. So we decided to disable the text algorithm by default



***********************************************************************************



If you need maximum possible compression ratio for plain text data



regardless of speed, you can enable the text compression



in "Advanced compression parameter" dialog. Press "Compression..."



button on "Advanced" page of archiving dialog to access it



You can also change this option permanently in default compression



profile;



*********************************************************************************



Fastest" (-m1) compression mode also supports several processor



cores now. In 4.11 it could use only a single processor core



RAR general decompression algorithm speed is slightly improved



though not to same extent as RAR compression. RAR decompression



is not able to use several processor cores, so its performance



does not depend on a number of cores



*********************************************************************************



Changes in ZIP compression:



**********************************************************************************



now ZIP compression supports several processor cores resulting



in noticeably higher performance in multi-core environment



Single CPU ZIP compression is also faster than in 4.11;



memory use for ZIP compression is increased to about 15 MB
