Table 2: Performance comparison of C++ and Golang proxy implementations vis-a-vis to the typical proxyless setting. Content and response current approximate sizes are in MB, while load times are in seconds and represented as a 95% confidence interval over 50 measurements done in different days and times. (4.18 s and 1.65 s) are rather insignificant.
