Winrar 4.20 (32bit And 64bit)
Whats New In v 4.20 ?
general pressure criteria is enhanced for better
utilization of several processer cores. While some rate gain
is possible even in individual processer method, best results
are obtained in multi-core atmosphere.
Speed obtain is determined by information type and regular quality.
Several cores are used more effectively when compressing
large data files.
b) we had to increase storage specifications to accomplish higher
compression rate. Common RAR pressure criteria allocates
about 120 MB evaluating to 40 MB in WinRAR 4.11;
c) RAR written text pressure criteria cannot implement several CPU cores
efficiently, so its performance in multiprocessor environment
is much reduced than for general criteria. Also its decompression
speed is much reduced than normally criteria regardless of
CPU variety. So we made the decision to turn off the writing criteria by standard.
If you need highest possible possible pressure rate for simply written text data
regardless of rate, you can allow the writing compression
in "Advanced pressure parameter" dialogue. Media "Compression..."
button on "Advanced" page of preserving dialogue to access it.
You can also change this option completely in standard compression
profile;
Fastest" (-m1) pressure method also facilitates several processor
cores now. In 4.11 it could use only just one processer primary.
RAR general decompression criteria rate is a little bit enhanced,
though not to same level as RAR pressure. RAR decompression
is not able to use several processer cores, so its performance
does not rely on a variety of cores.
