Class ParallelOptions

Class ParallelOptions

Namespace: Aspose.Zip.Saving
Assembly: Aspose.Zip.dll (25.2.0)

Options for parallel compression.

public class ParallelOptions

Inheritance

object ← ParallelOptions

Inherited Members

object.GetType(), object.MemberwiseClone(), object.ToString(), object.Equals(object?), object.Equals(object?, object?), object.ReferenceEquals(object?, object?), object.GetHashCode()

Examples 

using (var archive = new Archive())
{
    archive.CreateEntries("DirToCompress");
    archive.Save("archive.zip", new ArchiveSaveOptions() { ParallelOptions = new ParallelOptions { ParallelCompressInMemory = ParallelCompressionMode.Auto, AvailableMemorySize = 4000 } });
}

Remarks

These options manage simultaneous compression by several CPU cores.

Constructors

ParallelOptions() 

public ParallelOptions()

Properties

AvailableMemorySize

Gets or sets memory estimate in megabytes available to accomodate compressed entries without swap to disk. This value only makes sense if Aspose.Zip.Saving.ParallelOptions.ParallelCompressInMemory setting is in Aspose.Zip.Saving.ParallelCompressionMode.Auto mode.

public int AvailableMemorySize { get; set; }

Property Value

int

Remarks

This value is used to calculate biggest size of entry that can be compressed in parallel with others. All entries above the calculated threshold will be compressed sequentially. It is safe to have Aspose.Zip.Saving.ParallelOptions.AvailableMemorySize property as big as free RAM and even bigger. By default it is assumed you have at least 200MB per CPU core.

ParallelCompressInMemory

Gets or sets value indicating how parallel approach to be used.

public ParallelCompressionMode ParallelCompressInMemory { get; set; }

Property Value

ParallelCompressionMode
