防火墙性能一直是少数研究的课题。更少的工作甚至在分析防火墙性能的领域内完成。大多数情况下，可用的工作是加强与防火墙系统相关的配置管理，并检测是否遗漏了任何配置。Salah等人利用基于马尔可夫链的分析队列模型研究了防火墙的性能。采用这种方法分析了防火墙在DoS攻击下的通信量和攻击流量。Asmi等人(2012)对防火墙的几种操作进行了研究。在这项研究中，研究人员测试了各种防火墙的性能以及包括Cisco、ASA、包过滤和SPLAT检查点在内的安全包。

在性能方面，研究人员只考虑吞吐量以及最大并发关系数。调查结果表明，与研究中的其他类型相比，ASA Cisco具有较好的性能。当涉及到安全性时，他们进行了简单的测试，并报告说防火墙表现出了良好的抵抗性。
防火墙的实施对网络性能的影响已经被研究人员如。模拟结果表明，防火墙的使用提高了网络的显示和响应的平均时间。此外，他们还建议，使用并行性质的防火墙对于网络性能的改善是至关重要的。仿真结果表明，防火墙在整体上降低了网络性能。

Firewall performance has been a subject of study in only few studies. Lesser work is even done within the field of analyzing firewall performance. Mostly, the available work is of the consideration to enhance the management of configuration related to firewall systems and detect whether any configuration has been missed. The firewall performance has been studied by researchers such as Salah et al. through use of a model named, analytical queue model based upon the chain of Markov. Firewalls are analyzed by this methodology subjected to general flow of traffic along with the flow of attack for DoS. Several kinds of operations of firewalls were examined by other researchers such as Asmi et al. (2012). In the study, the researchers tested the various firewalls performance as well as security inclusive of Cisco, ASA, filter of packet and SPLAT checkpoint.

With regard to performance, only the throughput was considered by the researchers along with the maximum concurrent relationship number. The research results from the investigation depicted that ASA Cisco has a performance which is good in comparison to the other types involved in the study. When it comes to security, simple tests were performed by them and it was reported by them that firewalls have showed a good type of resistance.
The influence of firewall implementation over the performance of networks has been studied by researchers such as. Their results from simulation depicted that use of firewalls enhances the display of networks and average time from response. They suggested, moreover, that use of firewalls of parallel nature is essential for performance of network’s improvement. The results of simulation resulted in proving that firewalls result in degrading the network performance on the whole.
