g3proxy vs Squid

g3proxy has no write-up on Specifiction yet; its figures are above.

Squid is a self-hosted caching proxy for web traffic. It keeps commonly requested pages and other supported data available for reuse, helping reduce bandwidth and improve response times. Squid handles HTTP, HTTPS, FTP, and gopher data; supported cache engines also include ICP and HTCP. Administrators can apply access controls and use full request logging. Squid can accelerate servers, direct content among web servers, and organize content clusters for load balancing. Multiple caches can be connected as a mesh or hierarchy through parent and sibling links. Proxy authentication options include Basic, NTLM, Digest, and Negotiate, with bundled helpers for LDAP, SQL databases, PAM, RADIUS, and Windows domains. Basic authentication encodes credentials with Base64 rather than encrypting them, so credentials are effectively cleartext between browser and proxy. Squid is free to download, use, and modify, and is distributed under GPL version 2, with some components under compatible open-source licenses. It is available for Linux, macOS, and Windows, with installation through operating-system packages, source releases, and binaries. Documentation, a wiki, bug tracking, and mailing lists are available.
