compression_threshold - enables threshold for compression of data in the CIB

Because the CIB data is stored in XML, it is typically very bulky and highly compressible.

The compression_threshold directive tells Heartbeat at what size to begin compression of data. Compression can actually increase the size of small data items. This directive tells how big a CIB (in kbytes) should be the smallest subject to compression.

The general syntax of a compression_threshold directive is:

compression_threshold size-in-kbytes

A sample compression_threshold directive is shown below
