+**Concurrent blob uploads**
+`dlt` limits the number of concurrent connections for a single uploaded blob to 1. By default `adlfs` that we use, splits blobs into 4 MB chunks and uploads them concurrently which leads to gigabytes of used memory and thousands of connections for a larger load packages. You can increase the maximum concurrency as follows:
+```toml
+[destination.filesystem.kwargs]
+max_concurrency=3
+```

 ### Local file system
 If for any reason you want to have those files in a local folder, set up the `bucket_url` as follows (you are free to use `config.toml` for that as there are no secrets required)
