This metabase property specifies the size of the buffer, in bytes, that IIS will use to read uncompressed files. A larger buffer will yield slightly faster compression performance, but at the cost of additional memory usage.
HcIoBufferSize is used by IIS only if HcDoOnDemandCompression is set to TRUE. The maximum allowable value is 1,048,576 bytes (1 MB).
The Web service must be restarted before any changes to this property take effect.
