37 | ------------------------------
|

38 | - ISetProperties::SetProperties:
|
---|
39 | it's possible to specify desirable number of CPU threads:
|
---|
40 | PROPVARIANT: name=L"mt", vt = VT_UI4, ulVal = NumberOfThreads
|
---|
41 | If "mt" is not defined, 7za.dll will check number of processors in system to set
|
---|
42 | number of desirable threads.
|
---|
43 | Now 7za.dll can use:
|
---|
44 | 2 threads for LZMA compressing
|
---|
45 | N threads for BZip2 compressing
|
---|
46 | 4 threads for BZip2 decompressing
|
---|
47 | Other codecs use only one thread.
|
---|
48 | Note: 7za.dll can use additional "small" threads with low CPU load.
|
---|
49 | - It's possible to call ISetProperties::SetProperties to specify "mt" property for decoder.
