FAQ: Improving performance – speeding up load times and printing by using compression tools

As part of the internal security measures LockLizard only decrypts PDF documents directly into memory.  This requires the whole document to be decrypted so that, for instance, it can be searched.

Where large documents, and those with complex layouts, are being handled both decrypting and printing performance may be improved by using a PDF compressor such as FILEminimizer before protecting the document.  This can significantly improve load times as well as providing much better system performance.
