The increasing number of malicious web attacks has driven major corporations to have deployed multiple security measures including proxy servers, firewalls, multiple anti-virus scanning engines and encryption technologies against various types of cyber crime. While these measures are working 24/7 to keep the enterprise network safe, they system loads may eventually experience performance degradations due to high CPU workloads.
The reasons are simple. Proxy, firewalls and multi-scanning generate plenty of loads and the CPU has to handle all of the loads, such as encryption and decryption. Whenever a proxy server is performing its functions, it generates a substantial load onto the servers, and the CPU is required to encrypt and decrypt the loads. Whenever a firewall is on duty, it generates high CPU flows due to traffic management, packet inspection and options screening. Lastly, to ensure zero-conflicts during multi-scanning against viruses, the CPU must be at optimal state to process all the requests to avoid system freeze.
