What are the downsides for this system?
- null0pointer 2y agoIt’s probably extremely slow. But that’s the price you pay for resilience.
- sebubu 2y agoCreator here. It takes around 30ms to resolve a public key DNS entry on the DHT. After the first resolution, the entry is obviously cached according to the configured time-to-live (ttl). It's not as fast as regular DNS, 30ms is still very quick.
- null0pointer 2y agoWow that is pretty quick. I’m glad to hear it.
- rklaehn 2y agoWe use pkarr at iroh.computer for node discovery. It is anything but slow. It is very rare for a lookup to take more than a few milliseconds. It is sometimes faster than our non-p2p node discovery option which is using DNS. DHTs get a bad rap because of many recent DHTs that were horribly inefficient. But mainline is different. Many of the design decisions of mainline seem very limiting at first, but make a lot of sense for perf. E.g. a pkarr record can only be 1000 bytes, so the entire message fits into a single non-fragmented UDP packet.
