Now, for a given endpoint, we have peaks of around 10 req/sec which is way more reasonable.
Furthermore, we are not hammering anymore our backend with requests on objects that are not here.

After discussing with the developpers, it is possible to go even further by running Peergos without IPFS:
this is what they do for some of their tests. At the same time, if you increase the size
of a block, you might have a non-federated but efficient end-to-end encrypted "cloud storage" that works over Garage,
with your clients directly hitting the S3 API!
If federation is a hard requirement for your, the next step would be to gradually allowing back our node to connect to the IPFS network,
while ensuring that the traffic to the S3 cluster remains low. For example, configuring our IPFS
node as a `dhtclient` instead of `dhtserver` would exempt it from answering public DHT requests.
Keeping an in-memory index (as a hashmap and/or blum filter) of the blocks stored on the current node

We have identified that the main problem is linked with the DHT service,
and proposed some improvements (disabling the DHT server, keeping an in-memory index of the blocks, using the S3 backend only for your data).

It is possible to modify Peergos to make it work without IPFS. With some optimization on the block size,
you might have a great proof of concept of an end-to-end encrypted "cloud storage" over Garage.
*Ping us if you make a prototype!*
From an IPFS design perspective, it seems however that the numerous small blocks handled by the protocol
do not map trivially to efficient S3 requests, and thus could be a limiting factor to any optimization work.
As part of our test journey, we also read some posts about performance issues on IPFS (eg. [#6283](https://github.com/ipfs/go-ipfs/issues/6283)) that are not
