On a small scale, the slowdown is not going to be a persistent drawback, but if you get into a high-end requirement with many concurrent connections this isn't a scalable expertise. Even at present, with extremely excessive performance, general-purpose CPUs and efficient working systems, software proxies nonetheless are most likely to have significant variation in efficiency in real-world environments.

Reporters, whistleblowers and security officers count on the added identification safety provided by proxy servers to protect themselves, sources, their firms, purchasers and partners.
