5. Conclusion
Acceleration and offload functions of Intel
®
QuickAssist Technology (QAT) demonstrated in this paper are encryption/
decryption and compression/decompression. IPsec tunneling was used as a workload to show the benefit of encryption
and decryption offload. QATzip was used to demonstrate the performance of accelerated compression
and decompression. In both cases, faster performance was offered by offloading operations onto the QAT engines.
Other workloads not shown are also beneficiaries of this technology, including web server applications.
