Disabling default compression has the benefit of speeding up access to data in whole document containers at the cost of increasing container size. Disabling default compression also removes the dependency on the ZLIB library. Compression can be disabled by deleting the preprocessor definition _DBXML_COMPRESSSION and the linker dependency zdll.lib from the project dbxml, then rebuilding the project. Be warned that containers created with default compression cannot be opened if default compression has been disabled.
