TL;DR In light of recent findings regarding the performance gain provided by Hydra peers in the IPFS network, which indicate that the gain is in the area of 10% (or less) and considering the substantial cost that Hydra’s operation incurs, Protocol Labs has decided to carry out a “Hydra Dial Down” ex…

Update: the Hydra Dial Down event will carry on as scheduled and announced above at 3pm UTC, tomorrow 1st December 2022. You can join #hydra-dial-down in the Filecoin Slack for more frequent updates. We’ll share here hourly or so updates after the dial-down.

Update: After some testing, which took a bit longer than expected, the DB part of the Hydras has been turned off at ~1730 UTC. Read and Write requests to Hydras have immediately gone down to 0, as expected. We’ll share first results shortly, when we have enough data to plot. Operation is continuing …

:mega: Update on results from the IPFS Network after the Hydra Dial Down TL;DR: Results indicate a slight performance hit when operating without Hydras in the network, confirming our expectations and previous results from emulated Hydra-less experiments. Measurement details: We’ve deployed nodes in…

Quick add on regarding the results we’re seeing and the higher than expected performance difference: we were expecting an average performance hit of ~10% in the Hydra-less environment. Instead, we’re seeing that this is closer to ~15% is some cases. We believe that the difference here is due to the …
