mmproxy, a PROXY protocol gateway. mmproxy listens for remote connections coming from an application level load balancer, and spoofs the client IP address. From the application’s point of view, this spoofed connection, coming through mmproxy, is indistinguishable from a real one, connecting directly to the application.

For use cases with a large number of threads or a large number of isolates (or
both), ThreadDataTable can be a major performance bottleneck due to O(n)
lookup time of the linked list. Switching to a hash map reduces this to O(1).

Example 1: Sandstorm.io, a Node.js app that utilizes "fibers", was observed
spending the majority of CPU time iterating over the ThreadDataTable.

Example 2: Cloudflare's Workers engine, a high-multi-tenancy web server
framework built on V8 (but not Node), creates large numbers of threads and
isolates per-process. It saw a 34x improvement in throughput when we applied
this patch.

DNS: Internet’s Directory - Nearly everything on the Internet starts with a DNS request. DNS is the Internet’s directory. Click on a link, open an app, send an email and the first thing your device does is ask the directory: Where can I find this?
Unfortunately, by default, DNS is usually slow and insecure. Your ISP, and anyone else listening in on the Internet, can see every site you visit and every app you use — even if their content is encrypted. Creepily, some DNS providers sell data about your Internet activity or use it target you with ads.
We think that’s gross. If you do too, now there’s an alternative: 1.1.1.1

Some of this was due to single large networks having reachability issues, for example a large operator in Germany has nearly 350 probes connected, all of them failing // I remember when RIPE debogonised 1/8 and 30% of the noise on 1.2.3.4 was down to T-Mobile NL's buggered SIP tackle
