IPFS very slow - also dht: checking dht client type: session shutdown notif.go:43

1

I started a node on digital ocean and I added data using

ipfs add filename

What happens is very simple context adds (eg one text line) but anything else is readable via ipfs cat hash but not at the https://ipfs.io/ipfs/hash. I get timeouts.

Here is an example - https://ipfs.io/ipfs/QmV3oNfZANPtjFF9WszgdYtPChdveN42tdmq8mZmierFDW

I also get this -
dht: checking dht client type: session shutdown notif.go:43

Has anyone any ideas about the reasons explaining this?

Finally this added - https://ipfs.io/ipfs/QmUsNKsyEWGVMYQCMyM9QCCgXXCuEXLbuh5EUjRza6pSp3 - it took 8 hours. Why so slow? What can be done to speed this up?
