JFScan: Extremely fast port scanning and service discovery tool based on Masscan and Nmap
About JFScan JFScan is an extremely fast port scanning tool based on Massacn and Nmap. This tool is designed to simplify various forms of port scanning tasks and can receive the following forms of scanning targets: URL, domain name or IP (including CIDR). In addition to this, we can also use parameters or STDIN to […]
9. idSpanMap uses radix tree instead of the original unordered_map 10. Performance comparison before and after using radix tree
9. idSpanMap uses a radix tree instead of the original unordered_map Our original idSpanMap used the unordered_map hash bucket in the STL container. Because the STL container itself does not guarantee thread safety, we need to lock it when accessing to ensure thread safety. This is the performance of the memory pool we wrote. bottleneck […]
