-Make sure repo is initialized with datastore backed by `badgerds` for improved performance, or if you choose to use slower `flatfs` at least use it with  `sync` set to `false`.
+Wikipedia has a lot of blocks, to publish them as fast as possible,

-**NOTE:** While badgerv1 datastore _is_ faster, one may choose to avoid using it with bigger builds like English because of [memory issues due to the number of files](https://github.com/ipfs/distributed-wikipedia-mirror/issues/85). Potential workaround is to use [`filestore`](https://github.com/ipfs/go-ipfs/blob/master/docs/experimental-features.md#ipfs-filestore) that avoids duplicating data and reuses unpacked files as-is.

-Configure your IPFS node to enable directory sharding
