How to Check If Compression with QATzip Library Is Properly Working with Intel® QuickAssist Technology (Intel® QAT)

• Performance issues observed with Intel® QAT during compression.
• Compression algorithm takes a long time to compress certain files and file types.

1. Install the QATzip library as instructed on the GitHub* page Intel® QuickAssist Technology (QAT) QATzip Library.
2. Use the following command to verify the library's functionality: # qzip -k $input_file
3. Check for the generated compressed file in the same directory where the command was run from.
4. Review the printed statistics for performance metrics. They look like the following example:

   Time taken:        588.162 ms
   Throughput:        30320.548 Mbit/s
   Space Savings:     75.547 %
   Compression ratio: 4.090 : 1

QATzip is a user space library that builds on top of the Intel® QuickAssist Technology user space library to provide extended accelerated compression and decompression services by offloading the actual compression and decompression requests to the Intel® QAT hardware.
