Benchmarking Suricata in Different Isolation Systems Using TCPreplay
Containers like LXC are becoming a popular solution to program isolation. Compared to virtual machines (VM), containers tend to have less resource overhead and higher performance, which makes it interesting to explore how much benefit we can get from deploying virtual network functions (VNF) with containers instead of VMs. Therefore, we conducted an experiment in which we compared performance and resource usage of Suricata, a popular multi-threaded IDS program, in bare metal, Docker container, and virtual machine setups, and in different load levels and resource allocation configurations.

For very long time I have been creating RAM disk and pointing temp and cache dirs there to improve I/O performance and reduce unnecessary SSD writes. Since Windows 8, changing the cache location of IE (a.k.a. “Temporary Internet Files”) to a RAM disk could result in crashes of Metro (a.k.a. “Modern”) apps, which I didn’t figure out why until recently. The problem is also observable in Windows 10.
