This metabase property specifies the size of the buffer, in bytes, that IIS will use for receiving compressed data. This buffer is used for both on-demand compression of static content, as well dynamic content compression. A larger buffer will yield slightly faster compression performance, but at the cost of additional memory usage.
The size limit specified by HcCompressionBufferSize is used by IIS only if either HcDoOnDemandCompression or HcDoDynamicCompression are set to TRUE. The maximum allowable size of the buffer is 1,048,576 bytes (1 MB).
The Web service must be restarted before any changes to this property take effect.
