After installing the WRS enhancement patch in Smart Protection Server (SPS), SPS will convert a new format of the Web Blocking List (WBL v2.0), which will then consume more hard disk space after pattern download for better system memory and network bandwidth usage.

WBL v2.0 will need an extra 2GB of space at first, though it may need more to keep the best protection as web threats increase. The estimated size will be 3GB by 2014.
