4.34 beta 2006-02-27
|
|
------------------------------
|
|
- ISetProperties::SetProperties:
|
|
it's possible to specify desirable number of CPU threads:
|
|
PROPVARIANT: name=L"mt", vt = VT_UI4, ulVal = NumberOfThreads
|
|
If "mt" is not defined, 7za.dll will check number of processors in system to set
|
|
number of desirable threads.
|
|
Now 7za.dll can use:
|
|
2 threads for LZMA compressing
|
|
N threads for BZip2 compressing
|
|
4 threads for BZip2 decompressing
|
|
Other codecs use only one thread.
|
|
Note: 7za.dll can use additional "small" threads with low CPU load.
|
|
- It's possible to call ISetProperties::SetProperties to specify "mt" property for decoder.
|
